auc tests: adjust cosmetically to prepare for SQN changes

The current auc tests test a lot with SQN == 0. An upcoming change in the SQN
algorithms from libosmocore [1] will require us to pass desired_sqn - 1,
because the tuple generation will increment the SQN before calculating.  Later
on [2] we will also want to employ ind_bits and ind in the test. In order to
have some room in the number range, cosmetically adjust the current SQN tested
for from 0 to 32, changing the generated AUTN. The upcoming adjustment to the
new situation will then be able to show that only the SQN values before and
after vector generation change while the auth tuples as well as the SQNs used
for generation remain the same (without having to trick around with wrapping
SQN past its maximum value).

Note that the TS 55.205 test sets include neither SQN nor AUTN. While AUTN
changes with changing SQN, all the other values are invariant of the SQN used.
So we can simply choose a different SQN and ignore the difference in the AUTN.

[1] change-id Iadf43f21e0605e9e85f7e8026c40985f7ceff1a3 "store last sqn"
[2] change-id Ibc97e1736a797ffcbf8c1f7d41c5c4518f4e41bf "fix SQN increment"
