open prop(os): EFISTUB installation #6

Add capability to installer to add kernel directly to motherboard UEFI menu via EFISTUB Ubuntu can be booted this way, RL is a derivative of this distro so the capability should be there, just make it easier for the end user in the case that they dont want to use a bootloader.
