gnu: light: Install udev rules to allow sudo-less invocations.
* gnu/packages/linux.scm (light)[arguments]: Substitute the absolute paths of chgrp and chmod in 90-backlight.rules and install the rules file to the special lib/udev/rules.d/ directory of the out output. This allows for any member of the video group to set brightness using light without sudo. Signed-off-by: Efraim Flashner <efraim@flashner.co.il>
