Specfile reconciliation.
    
    As described in https://pagure.io/waiverdb/issue/90, I modified the specfile in
    Fedora's distgit to produce a separate cli subpackage, but didn't update the
    specfile in our repo here.  This brings those downstream changes back upstream
    to try and reconcile the two copies.
    
    Long-term, I agree - we want to move the waiverdb-cli tool out into its own
    python module.  This commit and PR are just to get our divergent copies back in
    line.
