auth: verify test sets from 3GPP TS 55.205
Put to-text conversion of the 3GPP TS 55.205 PDF's section defining the test
vectors in tests/auc/gen_ts_55_205_test_sets/ts55_205_test_sets.txt and add
python script to generate auc_ts_55_205_test_sets.c from that at build time.
The generated auc_ts_55_205_test_sets.c runs through all 19 test sets,
verifying that our gsm_milenage() matches the reference data.
