    backend: call creatrepo_c with --update if possible
    
    Even for the full createrepo run.  The large projects are simply too big
    to run non-cached createrepo_c there.
    
    We actually never needed the full, non-cached createrepo run.  In case
    we need this in future, we can add another option (e.g. --no-caches).
