Specify dev nodes list file for ramdisk partition generation
Ramdisk partition requires "-n" argument to be passed when generating
the image file. Given that the value is agnostic to the target product
and is set to a constant value, this is implicitly set internally in
filesystem module.
Test: inspect ramdisk.img build command
