Fix kernel init.d support

The active project variable was missing, so it couldn't find the folder ;). I tested it, and it works in my kernel for M8!

Can there be an option to leave the ramdisk unpacked after adding this, or at least a note to indicate to do this last, since it'll repack it?

Thanks again for the fantastic kitchen! Now I just have to figure out why I have no bootanimation when using it . . .
