sshpeer: allow doublepipe on unbuffered main pipe The output pipe does not have manually managed read buffer (actually, no read anything). To also use the doublepipe for outgoing write (useful to consume remote output when pushing large set of data) we need the doublepipe to work on standard pipe too.
