veth: Add updating of trans_start
Since commit 21a75f0915dd ("bonding: Fix ARP monitor validation"),
the bonding ARP / ND link monitors depend on the trans_start time to
determine link availability. NETIF_F_LLTX drivers must update trans_start
directly, which veth does not do. This prevents use of the ARP or ND link
monitors with veth interfaces in a bond.
Resolve this by having veth_xmit update the trans_start time.
