Make netstat(1) more closely follow documented behaviour. If a TCP

socket in LISTEN state happens to be bound to an interface, it will
show up in netstat(1) output even without the -a switch.

As the definition of "sockets used by server processes" is a
difficult one to qualify with regards to UDP, do not change the
output behaviour for UDP sockets.
