[Migrated] Exclude pre-compiled packages matching excludes list

[jneves]

Originally from: Miserlou/Zappa#2075 by MickaelBergem

Description

There are some locally installed packages I don't want to install on my lambda function, such as coverage or mypy. They are in the excludes but somehow are still included in the final ZIP. This change prevents ignored packages from being included in the final ZIP file, resulting for me in a 30% reduction of the lambda size.

This works fine for me locally using Python3.7 and Python3.8

One caveat I just discovered is that patterns (like packagename*) will not be interpreted and will be used as plain strings.

Resulting output:

GitHub Issues

I have not opened a GitHub issue first, I'm happy to do it if it's really required, but a PR likely describes more what I want to do :)
