conformance: add a test that tries to chowning a volume

Add a conformance test that attempts to "chown" a volume declared in a base image, which produces different results depending on whether we're using the BuildKit-based builder or the V1 "classic" builder. For now, don't try to change our behavior, and continue imitating the behavior of the classic builder. Signed-off-by: Nalin Dahyabhai <[email protected]>
