ccs-python test broken by removal of distutils module in Python 3.12

[Paul Hargrove]

Recent automated regressions testing has begun to fail to compile the ccs-python test on some of our macOS systems where Homebrew has updated Python 3.12.

The failure output includes

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'distutils'

A quick Google search reveals that distutils was deprecated in Python 3.10 and 3.11, and removed in 3.12. See PEP 632

[Paul Hargrove]

The impacted macOS systems are now using Python 3.11 to avoid this issue, though use of Apple's /usr/bin/python3 would also have been sufficient. Since this issue only impacts a maintainer-mode test, this work-around is not needed in general.
