cros: Support initramfs netboot install
For netboot factory install, we are moving from initrd to initramfs.
This requires a different boot command. The new boot command assumes
initramfs netboot by default and only load ramdisk image if 'has_initrd'
is set to 1 in environment variable.
BUG=chrome-os-partner:17368
TEST=On Spring, set server IP and boot. Finish the factory install
process. Boot without server IP set, and see u-boot boot from USB/eMMC.
