In order to dual boot Windows and ChromeOS, Windows must
not find a GPT partition table on the disk. So change
ChromeOS to cope with an alternative signature "CHROMEOS"
instead of the standard "EFI PART"
BUG=chrome-os-partner:6108
TEST=rebuild chromeos, install it,
run cgpt legacy /dev/sda
dd if=/dev/sda of=/tmp/x bs=1k
hexdump -C /tmp/X
see the string CHROMEOS
BRANCH=link
