Adjsut patch to source fedora-messaging-logger
    
    Right now when rawhide runs it checks out the releng repo and calls it
    like:
    
    . ./releng/scripts/fedora-messaging.sh
    
    but this fails:
    
    ./releng/scripts/fedora-messaging.sh: line 35:
    ./fedora-messaging-logger: No such file or directory
    because the logged is not in the current directory.
    Change it instead to use the same patch it's using for the sourcing.
