pip: topologically sort generated modules based on dependencies

What is this for?

This correctly orders the packages e.g. with https://github.com/flathub/org.pgadmin.pgadmin4/pull/53 I need to do some manual steps after creating the pip file.

1. Fix ordering in one instance
2. Add backports_zstd (python version depended)

This fixes step 1 right now

The link isn't telling me much. What was sorted incorrectly before?

In that example, python3-passlib gets put behind python3-paramiko

If I move it to the location on the left, it will work

Otherwise it fails with:

Requirement already satisfied: markupsafe>=2.1.0 in /usr/lib/python3.12/site-packages (from Flask-Security-Too==5.6.*) (3.0.3)
INFO: pip is looking at multiple versions of flask-security-too to determine which version is compatible with other requirements. This could take a while.
ERROR: Could not find a version that satisfies the requirement passlib>=1.7.4; python_version < "3.13" (from flask-security-too) (from versions: none)
ERROR: No matching distribution found for passlib>=1.7.4; python_version < "3.13"

Which points to https://github.com/pallets-eco/flask-security/blob/5.6.2/pyproject-too.toml#L46 as the reason. I guess being able to just call the app, with the targeted python version would be better, but that has it's own problems.

That is not happening due to sorting but the environment constraint.
