Accepting request 989214 from home:bnavigator:branches:devel:languages:python

- Setuptools itself does not depend on packaging anymore, only for
  pythondistdeps.py, That dependency will move to
  python-rpm-packaging soon. -- boo#1178257
- Use "setuptools" for building again.
  * Python 3.12 will drop the distutils fallback
  * Use the python-base vendored pip in a venv
  * Drop no-legacyversion-warning.patch
- Remove nonsensical python362 flavor check.
