Clarified that the signature's buffer size, `s`, is not used as an
IN parameter.
Under the old docs, the only thing stated was "at most
EVP_PKEY_size(pkey) bytes will be written". It was kind of misleading
since it appears EVP_PKEY_size(pkey) WILL be written regardless of the
signature's buffer size.
(cherry picked from commit 6e6ba36d980f67b6e5c7b139f78da7acbbf8ec76)
