The plain NEON implementation of AES is only suited for v8 cores that lack
the ARMv8 Crypto Extensions but have an implementation of the NEON tbl/tbx
instruction that is not pathetically slow. Unfortunately, this is currently
the empty set, so there is no point in including this implementation by
default. So disable it.
