Change update logic to be backwards compatible with old format.

The key change is transforming var/...* to var_new/...* and dev_image/...* to dev_image_new/...* so that the tar file can be directly extracted to the stateful partition and have the same format for chromeos_startup as the old format.

Change-Id: I0148ae76bd664e3cc4b7762c23513ceac38d517e

BUG=8885
TEST=Tested with other CL by running stateful_update on a VM
