Add tests for krb5int_c_combine_keys

krb5int_c_combine_keys is used only by SAM-2 preauth with neither the
send-encrypted-sad nor use-sad-as-key flags, so it isn't covered by
any automated function tests.  Add some unit tests to make sure that
it works and returns the expected results for two randomly generated
test vectors.
