            Log:
            test if blueman-mechanism can read ~/.local/lib/python*/site-packages/

The use of blueman-mechanism service revealed that SELinux prevents
the blueman-mechanism process from reading the content of
/root/.local/lib/python3.10/site-packages/ directory. The TC reproduces
the situation.

Because the blueman-mechanism program is written in Python, it makes
sense to look for locally installed Python modules. In order to
support the basic Python principles, I believe that SELinux policy
should allow this access. The TC looks for appropriate policy rules
and file context patterns.

The TC covers BZ#2027044.
