[UPDATE][I3] Remove redshift-gtk service target

Because I start the tray icon at i3's startup in my configuration file,
I do not need to add redshift-gtk as a requirement to systemd's default
target. This avoids having two redshift-gtk instances running.

I also removed the systemctl calls to enable the services from the
installation script. Maybe I'll switch back to using services instead of
launching the tray-icon at i3's startup someday.
