With this change we'll open the shell's tty right from machined and then pass it to the transient unit we create. This way we make sure the pty is opened exactly as long as the transient service is around, and no longer, and vice versa. This way pty forwarders do not have to deal with EIO problems due to vhangup, as the pty is open all the time from the point we set things up to the point where the service goes away.
