osmo-auc-gen: umts: add --ind arg
During UMTS AKA, the caller typically indicates which IND slot the next used
SQN should belong to. Without this option, osmo-auc-gen will always produce SQN
from IND-slot 0. Add --ind option.
Enhance the osmo-auc-gen_test.sh to expect errors with useful printouts on
stderr, and add tests that verify valid --ind ranges.
