signer: update legacy bootloader templates after image signing

Specifically, this patch updates 'root_hexdigest' in legacy bootloader
templates in EFI system partition to match the signed rootfs.

BRANCH=None
BUG=chromium:512940
TEST=Ran sign_official_build.sh locally and booted the image on kvm
(using BIOS).
TEST=Ran signing_unittests.py by locally changing vboot_stable_hash to
include this patch.

$ ./sign_official_build.sh base chromiumos_base_image.bin \
  ../../tests/devkeys chromiumos_base_image_signed.bin
