stats: expose relayProtocol on prflx candidate

This makes relay candidates identifiable in scenarios
where the TURN server is behind another entity and the peer
sees a different ip address:

client -> turn -> relay address -> third party relay + address -> peer

In those cases, the relay candidate will become peer-reflexive
since the peer sends the third party relay's address in the xor-mapped
address and it is currently not easily possible to determine this is a
relay candidate anymore.
