Silence dnf repoquery output when resolving dependencies
    
    standard output of fedora-review printed this kind of lines many times:
    
    Last metadata expiration check: 0:00:09 ago on Tue Mar 23 19:31:22 2021.
    Last metadata expiration check: 0:00:19 ago on Tue Mar 23 19:31:22 2021.
    Last metadata expiration check: 0:00:22 ago on Tue Mar 23 19:31:22 2021.
    Last metadata expiration check: 0:00:25 ago on Tue Mar 23 19:31:22 2021.
    
    The reason was missing -q ("quiet") parameter from one call to
    dnf repoquery. Other repoquery calls do already use -q, so it is added
    to the outlier also. After the change, output is clean.
