    Fix bug breaking local builds.
    
    This bug was reported by @nphilipp here https://bodhi.fedoraproject.org/updates/FEDORA-2018-c9c3a37d96
    
    The issue is that the `record_filtered_rpms` method returns a new xmd
    buildrequires block, but whole buildrequires entries were omitted in the return
    value for local builds.  This one-liner includes them again.
