ss: handle seqpacket type of unix domain socket

ss didn't distignish seqpacket type from dgram type.
With this patch ss can distignish it.

 $ misc/ss -x -a | grep seq
 u_seq  LISTEN     0      128    /run/udev/control 10966                 * 0
 u_seq  ESTAB      0      0                    * 115103                * 115104
 u_seq  ESTAB      0      0                    * 115104                * 115103

tcp_metrics: Show source-address when displaying metrics

As the source-address is now part of the tcp-metrics, "ip tcp_metrics"
should display these too.
