This commit disables root autologin for postmarketos-base and enabled
root autologin for postmarketos-ui-weston (since weston-launcher is not
built, weston can only be run by root).
Having it in boot doesn't actually work, the service is being started
too early and fails. This change moves it to the default runlevel. This
change also removes "wifi-handler" since that service doesn't actually
exist.
