They aren't, DUN server register a server, through
bluetooth_register_server(), there is no UUID on this. Only DUN Service
register itself as DUN on BlueZ.

It doesn't need because it doesn't have one. We use DUN_GW_UUID here because
we want plugins/bluetooth.c to notify us when a DUN_GW device appears so then
we can use or DUN Client (dundee) to connect to it.

HFP does the same, in the Handsfree side we register for the UUID of the
Gateway side because you want to know about new HFP  gateways on the system.
