[patch proposal] LEDs in firstrun

Hi,

on a lime2 the firstrun script hangs as it doesn't seem to have a red or blue LED.
So I'd like to propose the following change which shouldn't break anything but add the green one. Unless some vendor adds even more colors.

Not sure if the trailing "|| true" is the best solution to make sure the script will never fail?
