Add systemd services for some background tasks

Add a ‘wm.target’ file that services can hook into and that Herbstluftwm starts
at the end of its startup script. This way different services can be sure that
the window manager itself has started up, and can be dependent on one another.
Hopefully this makes managing these background processes easier.
