osmo-auc-gen: umts: use default of ind_bitlen = 5 instead of 0
Most USIM out there seem to use IND-length = 5 bits, so do sysmousim-sjs1.
Currently from initialization we are using an IND length of zero in
osmo-auc-gen, which produces confusing SQN results after AUTS:
Where want SQN to be incremented to the next IND array, usually +32, an IND-len
of 0 makes for only +1.
As result, the osmo-auc-gen_test.sh produces SQN 32 instead of 24 after
receiving SQN.MS = 23 from AUTS: adjust test expectations.
