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. Allow to deploy it alongside the image by setting
'IMAGE_BUILDINFO_DEPLOY' to '1'.
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`.

@Paul Barker:
I missed your reply, sorry! Adapted the patches according to your comments
now.
v2:
* rebased
* copy generated file instead of regenerating it
* add varflags only if needed
