Key{Mint,Master} VTS: fix incremental AES tags

Change Id62fdce65131ee00c88e5849955a937f1c171748 split up the AES
incremental encryption tests into individual tests for each encryption
mode.  This meant that each generated key is only valid for a single
mode, which in turn means that for non-GCM mode keys it is not valid
to specify MIN_MAC_LENGTH.
