Fix deprecated displayManager.auto.enable option

Since a while[1], the services.xserver.displayManager.auto option is
deprecated. Since first of all SLiM got removed and now every display
manager supports auto-login, I switched the labtops module to use the
LightDM implementation.

Since the common x11 test module still exposes a similar interface, we
only need to use the same options from the test-support option, which
should hopefully be a "sane default" suitable for tests.
