wolfssl: disable AES-NI by default for x86_64
WolfSSL is crashing with an illegal opcode in some x86_64 CPUs that have
AES instructions but lack other extensions that are used by WolfSSL
when AES-NI is enabled.
Disable the option by default for now until the issue is properly fixed.
People can enable them in a custom build if they are sure it will work
for them.
