make_dev_ssd.sh: support updating legacy boot partitions

Browse Source 
Change the boot default option in partition 12 (ESP) when we want to disable
rootfs verification.

BUG=chromium-os:12424
TEST=./make_dev_ssd --remove_rootfs_verification --recovery_key -i USB_IMAGE
     # the image is bootable by H2C and H2C BIOS(EFI).
     # Not tried on non-EFI (syslinux) firmware, but it should work.
