The "post-install" program (normally /system/postinst) is a program
stored in the new system but executed from the old system right before
finishing the update. This post-install step provides a way to perform
device-specific tasks needed for old devices to accept the new update
*before* attempting to boot it.
Currently, we don't require any particular task to be performed in this
step, so this is just an example post-install program with some
documentation. Nevertheless, update_engine payload major version 1
requires a /postinst script in the system partition. While we plan to
use payload major version 2 in Brillo, this patch allows to push images
to the pre-release version of update_engine.
Bug: 24194445
Test: `m` includes /postinst in a Brillo target.
