rcar-gen3: Add a bad update bundle

This is a sample for bad bundle to demonstrate the roll back feature.
The image which removed the /sbin/init will fail to boot. It will
go back to the last success rootfs after several failures.

To build this bundle, add to local.conf:
    DISTRO_FEATURES_append = " bad-bundle"

and run:
    $ bitbake bad-agl-demo-bundle
