libpayload: add support for vboot_handoff
The vboot_handoff structure needs to be parsed from the coreboot tables. Add a placeholder in sysinfo as well as the ability to parse the coreboot table entry concering the vboot_handoff structure. Built with unified boot loader and ebuild changes. Can find and use the VbInitParams for doing kernel selection.
