buildrom: Add GRUB2
Many thanks to Patrick Georgi for his excellent work! This adds GRUB2 - enough to get to the GRUB2 prompt. Detailed configurations and more modules coming later.

As per IRC, this needs updates.

I'd personally drop at least hello and fat, the image is pretty big already (170 KB) which will cause problems with small 256KB ROM images (with normal/fallback even more).
Maybe we should add a kconfig string field where the user can specify the list of modules (later). And/or at least provide a "rescue", "minimal", "full" payload config option...
