Remove the non-OCI version of the configuration structure, and the
parent image ID, from the ImageData that libkpod returns.
At runtime, cri-o is only ever going to use the OCI configuration
(possibly converted from another format by the image library) when
setting up a container, so it can be confusing to display settings in
"kpod inspect" that might be discarded when we try to run a container.
Remove the non-OCI version of the configuration structure, and the
hard-coded Type field, from the ContainerData that libkpod returns.
