[SocketCAN] Emulate ACK if IFF_ECHO not set #56

See https://github.com/I-CAN-hack/automotive/issues/52 for more details.

tl;dr: Fake ACKs from the kernel waste space in the RX queue, causing dropped messages if many messages are sent simultaneously. Emulate ACK on rust side to keep space in RX queue for real messages.
