Add cups-browsed into ELN and F38 comps
    
    There will be a new package - cups-browsed - which was previous part of
    cups-filters package. It is useful for automatic installation of many
    remote printers (usual use case on server), so it would be great if the
    package was added to `print-server` (in ELN) and `printing` (in F38)
    comps groups.
    
    This is a part of self-contained change
