osmo-auc-gen: cosmetic: clarify output upon AUTS

When calculating a re-sync vector using AUTS, osmo-gen-vec used to print
SQN.MS + 2, the new SQN after vector generation, labeled 'SEQ.MS'.

Firstly, s/SEQ/SQN.

Secondly, print SQN.MS as umts.sqn - 2, which is the actual SQN recovered from
the AUTS. As explained in the comment, SQN.MS + 1 is used to generate the
vector, and then umts.sqn is increased a second time to indicate the next SQN.

With AUTS calculated from SQN.MS == 23, the output was:

  AUTS success: SEQ.MS = 25

Output now:

  AUTS success: SQN.MS = 23, generated vector with SQN = 24, next SQN = 25
