macbook: add keyboard backlight key bindings and permissions

- Add XF86KbdBrightnessUp/Down keybindings (Macbook-only) using swayosd
  for consistent OSD behaviour with screen brightness and volume
- Enable hardware.acpilight for udev rules allowing video group to write
  to /sys/class/leds/ (keyboard backlight)
- Add fred to the video group so brightnessctl/swayosd can write backlight values
