Fix panic when logging raw packets via sniffer.
Sniffer assumed that outgoing packets have transport headers, but
users can write packets via SOCK_RAW with arbitrary transport headers that
netstack doesn't know about. We now explicitly check for the presence of network
and transport headers before assuming they exist.
