FIPS: Don't allow SHA512-224 and SHA512-256 for ECDSA/DSA signatures

FIPS: Don't allow SHA512-224 and SHA512-256 for ECDSA/DSA signatures

These algorithms do not have OIDS (Note that RSA does have OIDS),
and are not valid values for FIPS.
Note that this was only possible if the "ECDSA" algorithm is fetched.
Note that "ECDSA-SHA512-256" and "ECDSA-SHA512-224" are not currently
fetchable.
