[gvfs/gnome-2-28] [gdu] Stop assuming that drives have no enclosing presentable

    [gdu] Stop assuming that drives have no enclosing presentable
    
    This makes the gdu volume monitor works with recent gnome-disk-utility
    versions with things like GduHub presentables that represents HBAs and
    Expanders. This will not affect previous gnome-disk-utility versions.
