also run easyconfigs test suite with Python 3.11

[boegel]

WIP because sdist tests fails with Python 3.11, because the CVS easyconfigs are not being included (cfr. #10326)

requires:

• rename CVS to ConcurrentVersionsSystem #18985

Looks like disabling pruning is no longer allowed, CVS files are excluded despite

[sdist]
# Don't remove CVS and RCS directories
prune = 0

sheesh python..

This is because, for setuptools >= 60, we are getting setuptools.setup instead of distutils.core.setup. This is part of the deprecation of distutils and moving people over to setuptools. From what I can tell, setuptools.setup does not have the prune option.

Starting point:

$ pip list
Package    Version
---------- -------
pip        23.0.1
setuptools 66.1.1

No CVS in dist:

• python3 setup.py sdist
• pip install setuptools==60.0.0 && python3 setup.py sdist

CVS in dist:

• SETUPTOOLS_USE_DISTUTILS=stdlib python3 setup.py sdist
• pip install setuptools==59.1.0 && python3 setup.py sdist
• pip uninstall setuptools && python3 setup.py sdist

Also, from the setuptools release notes:

• v59.7.0: Require Python 3.7
• v60.0.0: Setuptools once again makes its local copy of distutils the default. To override, set SETUPTOOLS_USE_DISTUTILS=stdlib.

From https://packaging.python.org/en/latest/guides/using-manifest-in/

After processing the MANIFEST.in file, setuptools removes the build/ directory as well as any directories named RCS, CVS, or .svn from the sdist, and it adds a PKG-INFO file and an *.egg-info directory. This behavior cannot be changed with MANIFEST.in.

I also could not find any indication in that documentation on how to stop it happening.
