Add Provides:systemd-resolved
    
    This is in preparation for https://src.fedoraproject.org/rpms/systemd/pull-request/52,
    splitting out systemd-resolved subpackage. The new package should
    be pulled in by comps, but this would create a "flag day", because
    the systemd-resolved name is currently unknown. So let's add the
    virtual Provides now. Even if the package is never split out, it doesn't
    cause any harm.
