can: dummy_can: dummy_can_init(): fix packet statistics

Browse Source 
The former implementation was only counting the tx_packets value but not
the tx_bytes as the skb was dropped on driver layer.

Enable CAN echo support (IFF_ECHO) in dummy_can_init(), which activates the
code for setting and retrieving the echo SKB and counts the tx_bytes
correctly.
