            Disable TlsConnectDatagram13.ClientCertCallbackBeforeServerFinished

SplitServerFinished calls Protect() internally to save the Finished
record for later injection.  In DTLS 1.3 this advances the server's
record sequence counter, so subsequent server records (Certificate,
CertificateVerify) arrive at the client with an unexpected sequence
number and are rejected with SSL_ERROR_RX_MALFORMED_HANDSHAKE.  The
TLS stream variant of the same test passes.  Skip the DTLS variant
until the test infrastructure is fixed upstream.
