add osmo-auc-gen_test

Add test for osmo-auc-gen invocations to ensure stability across upcoming SQN
increment scheme changes.

The test comprises of a shell script that invokes the osmo-auc-gen binary with
various milenage parameters, of which the stdout/stderr are verified.

More osmo-auc-gen invocations could be added, but my main focus is on the SEQ
changes. Instead of manually testing that it still works for each SQN patch, I
want this test to do it for me.

To make sure that osmo-auc-gen is build before the tests are launched, place
'utils' before 'tests' in the root Makefile.am.
