chacha20poly1305: use x/sys/cpu feature variables directly

Avoid using package specific variables when there is a one to one
correspondance to cpu feature support exported by internal/cpu.

This makes it clearer which cpu feature is referenced.
Another advantage is that internal/cpu variables are padded to avoid
false sharing and memory and cache usage is shared by multiple packages.
