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.
