    drive-menu: Don't assume mounts without volume are local
    
    The intention of the code is to only expose actually plugged in
    devices rather than network mounts, but the existing heuristics are
    based on GVolume and simply assume a local mount where there's no
    associated volume. Fill that gap by querying the ::remote filesystem
    attribute in that case.
