rhash: disable compile-time SHA-NI for x86_64 compatibility

Browse source 
Since e5b0cb6e70 rhash,
by default, hardcodes SHA-NI instructions at compile time.
However, these instructions are not available on older x86_64 CPUs.

In particular, rhash is a dependency of cmake, meaning that no cmake builds can run on CPUs
without SHA-NI instructions with the default configuration.

This patch disables SHA-NI in rhash.

Fixes https://github.com/NixOS/nixpkgs/issues/519825.
