Revert "prereq-build: add Python 3.12 support"

This reverts commit 7ceb76ca3a37ba6b722df39ba0838909fa7cf7b4.

Python 3.12 removes the distutils package and is therefore not
compatible. We have to check downstream what relies on distutils before
adding actual support for Python 3.12. Sorry for the noise.

With this in-place, the macOS CI job fails and turns things red, revert
for now.
