Workaround bad interaction with .pth files. (#16238)
Workaround bad interaction with .pth files. (#16238)

When setuptools installs a python module (as is done via python setup.py
install)  It puts the module into a subdirectory of site-packages and
then creates an entry in easy-install.pth to load that directory.  This
makes it difficult for Ansiballz to function correctly as the .pth file
overrides the sys.path that the wrapper constructs.  Using
sitecustomize.py fixes this because sitecustomize overrides the
directories handled in .pth files.

Fixes #16187
