[rng] Add NIST self-tests for Hash_df
NIST provides a set of known-answer tests for the Hash_DRBG algorithm,
which includes known answers for the derivation function Hash_df used
as part of Hash_DRBG. Hash_DRBG is not an Approved algorithm for ANS
X9.82, but the known answers for Hash_df (which is part of ANS X9.82)
can still be used as part of the conformance testing for ANS X9.82.
