Don't set NEON_FUNCTIONAL in the getauxval path.
NEON_FUNCTIONAL is set by default in crypto.c. Chromium calls
|CRYPTO_set_NEON_functional| before |SSL_library_init| and thus the
getauxval path for CPU-feature detection was resetting the functional
flag, even on broken processors.
This change means that, apart from the default, only
|CRYPTO_set_NEON_functional| will change the NEON_FUNCTIONAL flag.
