ss: Fix layout/output issues introduced by regression

This patch fixes the following issues which was introduced by me in commits:

    #1 (2dc854854b7f1b) ss: Fixed broken output for Netlink 'Peer Address:Port' column
    ISSUE: Broken layout when all sockets are printed out

    #2 (eef43b5052afb7) ss: Identify more netlink protocol names
    ISSUE: Protocol id is not printed if 'numbers only' output was specified (-n)

Also aligned the width of the local/peer ports to be more wider.

I tested with a lot of option combinations (I may miss some test cases),
but layout seems to me better than the previous released version of iproute2/ss.
