Subject: [PATCH v2 05/18] crypto: testmgr - add DH RFC 7919 ffdhe3072 test vector

The previous patch introduced support for the safe-prime groups specified
by RFC 7919. In order to test this functionality, add a corresponding
ffdhe3072 test vector to testmgr. The choice of ffdhe3072 over e.g.
ffdhe2048 is justified by the fact that the NVMe spec mandates it for its
TLS profile.

The test data has been generated with OpenSSL.

Note that this new entry provides test coverage for the recent change to
crypto_dh_encode_key(), which made it to skip the serialization of domain
parameters for known groups, i.e. those with
->group_id != DH_GROUP_ID_UNKNOWN.

Moreover, a future patch will make the DH implementation to reject domain
parameters not corresponding to some safe-prime group approved by
SP800-56Arev3 in FIPS mode and the existing DH test vectors don't qualify.
So this patch here will ensure that there's still some suitable test vector
available.
