Change the tethering upstream priorities.

We had mobile_dun before wimax, so if wimax ever dropped out we'd switch
to mobile_dun and never give it up.  Reverse the order so that mobile_dun
is the connection of last resort.  If wimax comes back we should now switch
back to using it for the tether upstream connection.
