Multiboot: remove multiboot tables generation.
GRUB2-as-payload doesn't use them. Libpayload can live with just coreboot tables
if loaded as payload. memtest86+ can use them but is buggy with them. Solaris
needs a huge boot archive not supported by coreboot and too big to fit in
flash (dozens of megabytes). All-in-all looks like no users are left for this.
