[PATCH v2 13/18] crypto: testmgr - add DH test vectors for key generation

[Nicolai Stange <nstange@suse.de>]

Now that all DH implementations support ephemeral key generation triggered
by passing a ->key_size of zero to ->set_secret(), it's certainly
worthwhile to build upon the testmgr's do_test_kpp() ->genkey facility to
test it.

Add two ->genkey DH test vectors to the testmgr, one for the RFC 7919
ffdhe3072 group and another one for the RFC 3526 modp2048 group. For the
resp. party B's keypair, just reuse the already available values
previously specified for party A in the existing known answer tests. This
will enable the compiler to merge these rather large data strings.
