This PR aims to fix an issue with timestamps of packets from VCAN sockets on aarch64

[polybassa]

More context. This PR solves an issue appearing on aarch64 kernel versions in combination with VCAN sockets. The function get_last_pkt_timestamp (

scapy/scapy/contrib/cansocket_native.py

Line 137 in 0dd08cd

return self.basecls, pkt, get_last_packet_timestamp(self.ins)

) returns an invalid time value for VCAN sockets on these kernel versions. This PR fixes it by using AUX data instead.
