Imply SKIP_KERNEL=1 when custom kernel file name is set (#235)

Browse Source 
Skip installation of kernel and .dtb files if the user has a
custom kernel.

Prevents users ending up with a bricked system that hangs on
rainbow screen, because the 4.9.x .dtb files do not work
with a 4.4.x custom kernel.
