retire testing aginst older LibreSSL versions

libressl prior to 3.4.x lack support for the EVP_DigestSign and
EVP_DigestVerify APIs that we need now that sshkey is converted
to EVP_PKEY.

If someone makes a good case for why we should support these versions
then we could bring back support with wrappers.
