ss: display pacing_rate/max_pacing_rate
Since linux-3.15, kernel exports tcpi_pacing_rate and
tcpi_max_pacing_rate in tcp_info
Add TCP pacing_rate information on ss -i output :
lpaa23:~# ./ss -ti dst 10.246.7.151

If SO_MAX_PACING_RATE is set on the socket, we add /max_pacing_rate as
in :
... pacing_rate 1570.5Mbps/2.0Gbps ...
