Let systemd track the tmux server it restarts

Browse Source 
Type=forking with no PIDFile left MainPID=0, so systemd read a crashed tmux
server as a clean exit and Restart=on-failure never fired. tmux -D runs the
server in the foreground, which gives systemd the real pid.

-D also turns exit-empty off, so the synthetic orchestra-runtime session is no
longer needed to hold the server open past its last agent pane. Nothing else
in the tree referenced that session.
