cros_generate_update_payload: Truncate rootfs to the filesystem size.
The delta_generator only updates the filesystem data, not the whole
partition. Currently, delta_generator code reads the size of the
filesystem and updates only that part. This patch resizes the rootfs
file before feeding it to the delta_generator in preparation for the
removal of the filesystem size computation in delta_generator.
