unify grub scripts under one directory
new commands are thus, build grub payloads: ./build grub payload (formerly ./build payload grub) build grub utils: ./build grub utils (formerly ./build module grub) The scripts is build/module/ will mostly be deleted. I say mostly, because some of them are being moved instead. The deleted ones will be ones that basically just run "make" in the target directory. They will be unified, in a follow-up patch.
