Race conditions could prevent /tmp/esp.* from being properly unmounted

sleep briefly and then retry.

The problem here is that most were doing their exiting w/in a subshell;
exit within a subshell kills the subshell, not the parent. Not all scripts
were using set -e (which would pick up the failing subshell); as such
just rewriting them to remove the potential via eliminateing the subshelling.
Beyond that, removed a couple of custom (working, although non-standard)
approaches, and removed a duplicate common.sh sourc'ing w/in mk_memento_images.sh
TEST=force 'find_common_sh' to fail, note the scripts fails to exit

The following pattern creates a race condition:
LOOP_DEV=$(sudo losetup -f)
...
sudo losetup "${LOOP_DEV}" "${ROOT_FS_IMG}"
If two steps similar to the above run in parallel, and both steps pick up
the same free loop device, they may try to mount different images with the
same loop device and one of the two stages will get a "device is busy" error.
To fix this, we should switch to the following pattern:
LOOP_DEV=$(sudo losetup --show -f "${ROOT_FS_IMG}")
This CL implements the above.`

When building a VM or USB-run image the boot args come from a preset template
which does not include the cros_debug flag. If this flag is present we maintain
it in this new boot configuration. The way we do it is by replacing the string
"cros_legacy" (which originates with the template) with
"cros_legacy cros_debug".
TEST=Build VM from a developer and test image and check grep "cros_debug"

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.
