Subject: [PATCH] ss: fix help/man TCP-STATE description for listening

There's some misleading information in --help and ss(8) manpage about
TCP-STATE named 'listen'.
ss doesn't know such a state, but it knows 'listening' state.

$ ss -tua state listen
ss: wrong state name: listen

$ ss -tua state listening
