gsm_utils: add enum osmo_rat_type, from osmo-msc enum ran_type
In the MSC, we have RAN types GERAN_A and UTRAN_IU, now we need a similar enum
in osmo-hlr's GSUP client.
Naming: in the MAP specifications, the RAN type is mostly called RAT type,
(Radio Access Network vs. Radio Access Technology?). Since GSUP is more about
MAP messages, I'm calling the enum osmo_rat_type.
Rationale: osmo-msc and osmo-sgsn want to tell the osmo-hlr which RAT a
subscriber is calling on. A subsequent patch will extend the GSUP protocol and
add a RAT types IE.
