rom.sh: Support SeaUBoot for 64-bit x86 U-Boot

Same concept as SeaGRUB, but for U-Boot. SeaBIOS starts, but
has a bootorder file loading U-Boot first, from flash.

You can interrupt it with the ESC menu, to boot something else
in SeaBIOS, including GRUB.

With this, we can effectively provide extremely user-friendly
UEFI-first setups in Libreboot.

Take that, edk2!
