umts aka: add sqn_ms out-param, print SQN.MS in osmo-auc-gen
When doing UMTS AKA with AUTS, it can be interesting to know the SQN.MS that
was encoded in the AUTS. The only way to know this is to provide it as a
separate out-parameter from milenage_gen_vec_auts(), because the SQN.MS from
AUTS stored in umts.sqn is immediately modified non-trivially by
milenage_gen_vec(). Add sqn_ms to struct osmo_sub_auth_data to retain SQN.MS
even after a vector was generated.
Use this to print out SQN.MS for 'osmo-auc-gen -3 -A'.
Adjust test suite expectations.
