cosmetic: refactor auc_compute_vectors(), add debug log

Make the generation logic easier to understand (hopefully).

Massively extend debug logging, which serves to illustrate the current AUTS
failure shown by auc_3g_test.

Since DAUC now logs the vectors, there is no need to print the vectors in
VEC_IS() in auc_3g_test and auc_ts_55_205_test_sets anymore. Adjust testlog
expectations accordingly.
