Minikube + Skaffold > 1.35 does not use Docker Remote API to build

### Expected behavior

When using skaffold with minikube WITHOUT Docker Desktop on local machine, skaffold should use the Docker Remote API in the minikube VM to build the image.

### Actual behavior

Since version 1.36 onwards, skaffold is unable to build the docker image with minikube if Docker Desktop is not available on the host machine. It keeps throwing this error

```
build [api] failed: exec: "docker": executable file not found in $PATH. Docker build ran into internal error. Please retry.
If this keeps happening, please open an issue..
```

### Information

- Skaffold version: 1.39.2 ( Broken since 1.36.0 )
- Operating system: MacOS
- Installed via: Homebrew
- Contents of skaffold.yaml:

```yaml
apiVersion: skaffold/v2beta29
kind: Config
build:
local: {}
artifacts:
- image: api
context: .
docker:
dockerfile: docker/Dockerfile-dev
deploy:
kubectl:
manifests:
- docker/k8s-job.yaml
- docker/k8s-pod.yaml
```

### Steps to reproduce the behavior

* Install skaffold with version > 1.35.
* Setup minikube without Docker Desktop (For example using hyperkit driver).
* Run `skaffold build` on any project that use `build.local: {}`.
