Go modules builder fails when using local module with provisioned.AL2 runtime

**Description:**
Using `sam build` in go projects with a dependency on a local module fails when the function runtime is `Runtime: provided.al2`

**Steps to reproduce the issue:**
1. create a new go application `sam init --name sam-app --runtime go1.x --dependency-manager mod --app-template hello-world`
2. Create a new module (here is the example I used). In a new folder called models, initialise a new module using `go mod init hello-go/models`

add a new go file called **person.go** add this code

```golang
package models

type Person struct {
FirstName string `json:"first_name,omitempty"`
LastName string `json:"last_name,omitempty"`
}

func (p *Person) FullName() string {

return p.FirstName + " " + p.LastName
}
```
3. Open the main.go file for the hello0world function. Import "hello-go/models" and replace the return statement with this

```golang

person := models.Person{FirstName: "John", LastName: "Doe"}

return events.APIGatewayProxyResponse{
Body: fmt.Sprintf("Hello %s, your ip address is %v", person.FullName(), string(ip)),
StatusCode: 200,
}, nil

```
4. Open the function go.mod file and add make sure the dependency is replaced to point to the local module

```
require (
github.com/aws/aws-lambda-go v1.23.0
hello-go/models v0.0.1
)

module hello-world

go 1.17

replace hello-go/models => ../models

```

5. Build the function `sam build`
6. If you run `sam local invoke "HelloWorldFunction"` you should see the output (with your IP address)

```
{"statusCode":200,"headers":null,"multiValueHeaders":null,"body":"Hello John Doe, your ip address is 127.0.0.1\n"}%
```

7. **Update the sam template to use Amazon Linux 2** instead of the managed runtime.

8. In the function definition replace handler and runtime properties, and the Metadata resource attribute

```yaml
HelloWorldFunction:
Type: AWS::Serverless::Function # More info about Function Resource: https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md#awsserverlessfunction
Properties:
CodeUri: hello-world/
Handler: bootstrap
Runtime: provided.al2
Tracing: Active # https://docs.aws.amazon.com/lambda/latest/dg/lambda-x-ray.html
Events:
CatchAll:
Type: Api # More info about API Event Source: https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md#api
Properties:
Path: /hello
Method: GET
Environment: # More info about Env Vars: https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md#environment-object
Variables:
PARAM1: VALUE
Metadata:
BuildMethod: makefile
```
9. Create a new Makefile in the hello-world function directory and add

```makefile
build-HelloWorldFunction:
GOOS=linux go build -o bootstrap
cp ./bootstrap $(ARTIFACTS_DIR)/.
```
10. Run `sam build`. The build now fails.

**Observed result:**

```bash
sam build
Building codeuri: /Users/sliedig/go/src/hello-go-al2/hello-world runtime: provided.al2 metadata: {'BuildMethod': 'makefile'} functions: ['HelloWorldFunction']
Running CustomMakeBuilder:CopySource
Running CustomMakeBuilder:MakeBuild
Current Artifacts Directory : /Users/sliedig/go/src/hello-go-al2/.aws-sam/build/HelloWorldFunction

Build Failed
Error: CustomMakeBuilder:MakeBuild - Make Failed: main.go:9:2: hello-go-al2/models@v0.0.1: replacement directory ../models does not exist
make[1]: *** [build-HelloWorldFunction] Error 1
make: *** [build] Error 1
```
**Expected result:**
I would expect the sam build system to correctly build my application irrespective of whether I am using go as a managed runtime or on AL2.

**Additional environment details (Ex: Windows, Mac, Amazon Linux etc)**
OS: Darwin x64 20.6.0
go version go1.17.1 darwin/amd64
SAM CLI, version 1.32.0

Reproduce the failure with sam build using the provided.al2 template, the function go.mod replacement, and the Makefile shown in the report. Start at the CustomMakeBuilder:CopySource and CustomMakeBuilder:MakeBuild steps, then verify that the local ../models replacement remains available during the build. Done means the same Go application builds successfully with provided.al2.
