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.

EVP_SignFinal() signs the data in B<ctx> using the private key B<pkey> and

places the signature in B<sig>. The number of bytes of data written (i.e. the

length of the signature) will be written to the integer at B<s>, at most
