Export pkcs1_prefixed_msg as RSA_add_pkcs1_prefix.

Platform crypto APIs for PKCS#1 RSA signatures vary between expecting the
caller to prepend the DigestInfo prefix (RSA_sign_raw) and prepending it
internally (RSA_sign). Currently, Chromium implements sign or sign_raw as
appropriate. To avoid needing both variants, the new asynchronous methods will
only expose the higher-level one, sign.

To satisfy ports which previously implemented sign_raw, expose the DigestInfo
prefix as a utility function.
