extmod/moduhashlib: Add namespace prefix for crypto-algorithms/sha256.h.

Browse Source 
Everyone loves to names similar things the same, then there're conflicts
between different libraries. The namespace prefix used is "CRYAL_", which
is weird, and that's good, as that minimizes chance of another conflict.
