The `buildinfo` file generated by the `image-buildinfo` class
contains useful information to identify an image. Having it in the
rootfs of the image as well as deployed alongside the image artifact
can be useful.
I use this in an automated testing workflow with unreliable deploy step
to ensure the deployment succeeded. With
IMAGE_BUILDINFO_VARS += "IMAGE_NAME"
IMAGE_BUILDINFO_DEPLOY = "1"
the generated buidinfo file is unique and the deploy step can be
verified by comparing (the hash of) the file on the booted system and in
`IMAGE_DEPLOY_DIR`.

v2:
* rebased
* copy generated file instead of regenerating it
* add varflags only if needed
v3:
* rebased
* deploy unconditionally as suggested by [email protected]
