ss: Dont show netlink and packet sockets by default

Browse Source 
Checking by SS_CLOSE state was remowed in:

    (45a4770bc0) ss: Remove checking SS_CLOSE state for packet and netlink

which is not really correct because now by default all sockets are seen
when do 'ss'.

Here is most correct fix which considers specified family.

To see netlink sockets:
    ss -A netlink

To see packet sockets:
    ss -A packet

And ss by default will show only connected/established sockets as it
was before all the time.
