Some services launched at bootstrap must be possible to override per
product. One such service is iitod, which manages the LEDs in Infix.
This change makes allows a product specific init script to clear the
led condtion, preventing Finit from lauching iitod. Also, rename the
ixinit-done condition to match the nomenclature used already.
