The previous patch introduced support for the safe-prime groups specified
by RFC 3526. In order to test this functionality, add a corresponding test
vector to testmgr. 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.
