* Update unit test for using the Python 2 collection loader path with

Python 3.

Skip the existing test on Python 3.12, since find_module is removed.

Suppress the pre-existing deprecation warnings using the Python 2
codepath with Python 3.

Add a test for Python >= 3.12, which doesn't call find_module.

* Ignore sanity test errors on systems without libselinux present.
