hs_pow: Replace libb2 dependency with hashx's internal blake2

This forgoes another external library dependency, and instead
introduces a compatibility header so that interested parties
(who already depend on equix, like hs_pow and unit tests) can
use the implementation of blake2b included in hashx.
