Update of bundled compileall2 module to 0.7.0
Adds the optional --hardlink-dupes flag for compileall2 for pyc deduplication This is explained in https://discuss.python.org/t/3014 and https://github.com/fedora-python/compileall2/issues/16 This option is not yet used anywhere. That allows us to backport this to all Fedoras but only use --hardlink-dupes on rawhide first.
