Clightd: add runit service
This PR adds a runit service for the Clightd backlight management daemon. In the unmodified config, `dbus` will automatically start `clightd` on demand, but, once started, the daemon will never die. (When `dbus` dies, the Clightd daemon doesn't die with it, it just repeatedly complains about a missing bus.) By starting the daemon from runit, its lifetime can be managed with runit.

A patch file from https://github.com/void-linux/void-packages/pull/20814.patch is attached
