blueprint: move vmdk towards lorax parity

The main difference (according to image-info) is an additional package
containing a gpg key which was used to verify packages. The one
generated by lorax-composer doesn't have this, because it doesn't verify
signatures.

Also, lorax generates an image with a separate /boot partition. This is
not yet addressed here, because osbuild doesn't support it yet.
