systemd: create our own graphical-session@.target

graphical-session.target is an existing target for the system. While I
don't use several X sessions, I prefer to have each service bound to
the right display and therefore, I create my own
graphical-session@.target for this purpose.

Also, I don't like having to use `systemctl --user enable`, so I
enable everything directly in graphical-session@.target. Other
dependencies are ordered from awesome@.service. This seems good
enough.
