Clarify return values for EVP_DigestVerifyFinal.
Previous language was unclear. New language isn't pretty but I believe
it is more accurate.

+EVP_DigestVerifyFinal() returns 1 for success; any other value indicates
+failure. A return value of zero indicates that the signature did not verify
+successfully (that is, tbs did not match the original data or the signature had
+an invalid form), while other values indicate a more serious error (and
+sometimes also indicate an invalid signature form).
The error codes can be obtained from L<ERR_get_error(3)>.
