Move Python related BuildRoot Policy scripts from redhat-rpm-config to python-srpm-macros
This allows us to maintain our own BuildRoot Policy scripts in an easier way. This change needs to be coordinated with the removal of the files from redhat-rpm-config. redhat-rpm-config requires python-srpm-macros, so no change is expected for the packagers.
