luci-base: add transitional /etc/init.d/ucitrack
Ship an /etc/init.d/ucitrack for spawning a virtual service with the sole purpose to track the configurations and dependencies formerly handled by luci-reload. Once all LuCI supported services ship with procd compatible init scripts, the uci track support can be dropped. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
