gprs_bssgp: abuse gsm48_encode_ra() to encode TAC
Both LAC and TAC take 2 octets and follow MCC/MNC fields on the wire.
We abuse gsm48_encode_ra() for encoding of MCC/MNC, but it can also
be abused to encode TAC in bssgp_create_rim_ri(). There is no need
to encode '0000'O and then override it with osmo_store16be().
