Introduce the script for generating sources tarball without a code under a license which was not yet approved for Fedora or RHEL

Change the name of the sources archive, so the maintainer will encounter an error when uploading new sources which haven't undergo modification by this script

Cherry-picked from Fedora: 7f8a0e15a6?branch=rawhide
