This change adds
- --rootfs_hash_pad to specify the MBs reserved for the pad
- the implementation of the above flag
- check if total fs size + pad size exceeds the partition size
- hash appending in make_image_bootable()
Fixes:
- a style for ROOT_FS_HASH usage
- bad mount|grep
- bad bash subst for root devices in all boot paths
- fixed a typo in the update_bootloaders table creation
- disables verified usb for now
Adding the padding argument ensures that the generated hash tree for the root filesystem is appended to the image. Assuming the rootfs is _never_ mounted read-write
again, that hash tree will be valid and vboot will be able to proceed.

Instead of playing mount and loop device games, this change adds support for
update_bootloaders.sh to directly update the EFI system partition living in the
image if a file, offset, and size is supplied.

Right now, the created arm.mbr is the size of the ESP
partition. It should be truncated though to just the mbr size.
In addition, dm= doesnt do anything on arm yet so replacing use with a todo and adding a check if it isn't there.

Adds two helpers that are not used yet. They will be
used in the next CL to unify the bootloaders in use
in build_image.
TEST=used in the next CL but otherwise not called.
