Packaging Python lambda layer fails to include platlib libraries (lib64)

### How did you install the Amplify CLI?

_No response_

### If applicable, what version of Node.js are you using?

_No response_

### Amplify CLI Version

latest

### What operating system are you using?

Amazon Linux 2

### Did you make any manual changes to the cloud resources managed by Amplify? Please describe the changes made.

Added a lambda function, edited the function, and pushed.

### Describe the bug

[This function](https://github.com/aws-amplify/amplify-cli/blob/8f632c20c5a0d6c0da819d7cd971a1856a1add40/packages/amplify-python-function-runtime-provider/src/util/packageUtils.ts#L16C10-L16C10) fails to include lib64 libraries when packaging up dependencies for execution on a Lambda function in service contexts. On Amazon Linux 2 (and some other Linux distros) platlib != purelib, so lib != lib64. All of the libraries in pipenv are necessary for executing Lambda functions, not just the purelib ones.

### Expected behavior

I would expect both lib and lib64 to be packaged up, but lib64 is ignored.

### Reproduction steps

Include a Python library with a platlib on Amazon Linux 2 (e.g. charset-normalizer, a dependency of requests) in an amplify-specified Lambda function. amplify push from an instance running Amazon Linux 2 where context.service is true (for example, one of the pre-provisioned build instances). The Lambda function will fail to import all lib64 libraries.

- [X] I have done my best to include a minimal, self-contained set of instructions for consistently reproducing the issue.
- [X] I have removed any sensitive information from my code snippets and submission.

Start with packages/amplify-python-function-runtime-provider/src/util/packageUtils.ts at the linked packaging logic, then reproduce the issue on Amazon Linux 2 with context.service set to true and a library such as charset-normalizer. Done means the packaged Lambda dependencies include both purelib and platlib libraries, including lib64 contents.
