python dependency: ensure that setuptools doesn't inject itself into distutils
We do not use setuptools for anything, and only lightly use distutils.
Unpredictable issues can occur due to setuptools monkey-patching, which
interferes with our intended use. Tell setuptools to simply never get
involved.
Note: while it's otherwise possible to check if the probe is run using
sys.executable and avoid forking, setuptools unconditionally injects
itself at startup in a way that requires subprocess isolation to
disable.
