EVP_Digest*: fix documented return values.

EVP_DigestSign{,Init,Update,Final}() and EVP_DigestVerify{Init,Update}()
always returned 1 for success and 0 for failure. EVP_DigestVerify()
and EVP_DigestVerifyFinal() can return -1 or -2, though.

Based on OpenSSL 1.1.1 56c59ddd99da05c2f30832cccaffb873a8481555
