connection: keep the raw port-forward local write at 120 s

Browse Source 
`SEND_TIMEOUT_OTHER` also bounded `forward.send` in
`try_port_forward_loop`, the write to the local target, whose own idle
timeout is an hour. Lowering it to 30 s made a target that stops
draining for half a minute drop the whole tunnel. That write gets its
own constant at the value it always had.
