These groups are terrible, we got the function wrong (unused ENGINE parameter does not match upstream), and the functions are unused. Unwind them. This change doesn't unwind the X9.42 Diffie-Hellman machinery, so the checks are still present and tested. (We can probably get rid of the X9.42 machinery too, but it is reachable from DSA_dup_DH. That's only used by wpa_supplicant and, if that code ever ran, it'd be ignored because we don't support DHE in TLS. I've left it alone for the time being.)
