The eclass code in distutils-r1_python_install makes some assumptions
specific to _distutils-r1_post_python_compile being called,
and scriptdir not being modified since. Make them more explicit by:
1) explicitly removing the files that we expect to have been created,
2) verifying that both the copied and the original scriptdir have
the same list of files.
