lit test broken for Python >= 3.12

[JohanEngelen]

Python 3.12 no longer has the distutils package.

❯ ./runlit.py -v .
Lit version:  18.1.6

See ultrafunkamsterdam/undetected-chromedriver#1641 (comment) for possible fixes. I don't have gdb so can't really test what replacement works for the version testing.

The testsuite has been forking fine for me with pythont3.12 (though I don't run the gdb or the valgrind tests). Perhaps you need pip install setuptools?

Depending on a package for two little version-string comparisons seems pretty silly IMO. Especially for nowadays uber-ancient gdb versions < 8. Ubuntu 20 has v9, Debian 10 v8. I guess we can simply remove those checks.
