Remove use of distutils

[QuLogic]

What does this PR do?

In main code, distutils can be dropped, as the version check is no longer necessary. In tests, it can be replaced by packaging.version.

Why was it initiated? Any relevant Issues?

distutils is deprecated and will be removed in Python 3.12.

Could the test fail in windows be related to the changes in this PR?

Let's see if it happens again on a restart.

OK, I'll drop the sysconfig commit for now, though it really should be a copy of the main one. I'll put that in #2422 instead.
