This mirrors rules_python to ensure that users can use execpath with a
py_binary target.

Fixes #455

it looks to me like this will break the ability to execute a container from this image - the entry point is gone. @thesayyn do you know if we have a test here that the py_image_layer can execute? Do we need to add a TestContainers Cloud or something so we have a docker daemon to run that assertion?

This will not affect containers, but i am afraid it might break PEX

# This is a special comment for py_pex_binary to find the python entrypoint.
# __PEX_PY_BINARY_ENTRYPOINT__ {{ENTRYPOINT}}
,

Under pex, the shell generated by py_binary is not used at all, and we invoke the main.py directly with the given interpreter. It would be good to manually test https://github.com/aspect-build/rules_py/tree/main/examples/py_pex_binary and confirm it doesn't break.

I tested it manually, and also added a commit here which does a simple genrule/assert_contains to automate that test.
