RSA: Use hashlen as the hash input size as documented
Where hashlen was previously ignored when the hash length could be
inferred from an md_alg parameter, the two must now match.
Adapt the existing tests accordingly. Adapt the sample programs accordingly.
This commit does not add any negative testing.
