For now we have only kernel LED trigger support. With this change it is now
possible to use application triggers.
If we configure a LED with a non kernel trigger, then we check on every
restart and boot of the LED service if we have this trigger as an application
in "/usr/libexec/led-trigger". If this file with the name is found, then we
execute this to init the LED.
Possible use cases are:
- Start/Stop/Restart an application led trigger service for this led
- Init a LED that is configured by a hotplug script (VPN tunnel established)

Set the default state for LEDs to off. When a trigger is set, the
trigger will turn the LED automatically on.
Currently LEDs might stay on, e.g. when the LED trigger is set to a
netdev trigger and the interface is never activated or the 'none'
trigger is selected without setting the 'default' option to 0 and it's
set for the LED indicating the system running state.
Using off as a default value is also consistent with the documentation
in the OpenWrt wiki.
