[compiler-rt][test] Use packaging.version.Version to compare glibc versions (#142596)

Instead of distutils.LooseVersion. distutils was depracated
(https://peps.python.org/pep-0632/) and has been removed in Python 3.12
(https://docs.python.org/3/whatsnew/3.12.html)

> Of note, the distutils package has been removed from the standard library.

packaging's version is able to handle glibc's major.minor:
https://packaging.pypa.io/en/latest/version.html#packaging.version.Version

> For these modules or types, use the standards-defined Python Packaging
Authority packages specified:
> distutils.version — use the packaging package

Relates to #54337
