gsup: send RAT type on LU
At 36c3, osmo-hlr was run with a patch that records the RAN type of attached
subscribers. Even though this is not in osmo-hlr master, it is nice information
to send along.
Note that the "Supported RAT Types" IE is used to send the actually attached
RAT. Could be a reason to not merge this to master as-is.
