Remove mention of link between message digests and public key algorithms.

The comment in EVP_DigestInit.pod is:
"EVP_MD_pkey_type() returns the NID of the public key signing algorithm
associated with this digest.  For example EVP_sha1() is associated with
RSA so this will return NID_sha1WithRSAEncryption.  Since digests and
signature algorithms are no longer linked this function is only retained
for compatibility reasons."
So there is no link anymore.
