Manuel Pégourié-Gonnard ebef58d301 OID + misc crypto: use MD_CAN and fix failures
After this, only PK, X.509 and TLS remain to be done.

Deterministic uses HMAC-DRBG which uses MD, so it needs crypto_init()
when using a driver-only hash.

Also, remove a special-purpose macro that's no longer needed.
