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.
