[images] Pre-install update package
This change includes the update package in the blobfs image and
the dynamic index. This has a few benefits:
* The merkle root of the update package is currently the best indicator
of the OS version since it includes references to the kernel images,
all monolith packages, and the system_image package. Without
requiring it to be present, the system cannot reliably use it as the OS
version.
* If an OTA attempt needs to download the update package, it assumes it
needs to apply the kernel image, causing the first OTA attempt after a
pave to always reboot, even if the kernel hasn't changed.
* The end result of an OTA and a pave are more consistent. The update
package will always be present after an OTA, and it will now be present
after a pave as well.
Test: pave, OTA, verify update does not download blobs or reboot
