Refactor the copying of xxmodule.c in distutils tests (#12141).
I need to copy this file in another test too, so I moved the support
code to distutils.tests.support and improved it:
- don’t skip when run from the Lib/distutils/tests directory
- use proper skip machinery instead of custom print/return/test suite
fiddling.
