Create a Makefile target to test the reproducibility of the project container using diffoci[1]. This tool provides a way to test for reproducibility of OCI containers by virtue of being able to display the diff between two versions of a container. It also allows for omitting some uninteresting diffs such as timestamps (with the `--semantic` flag). This is an early prototype as the setup currently introduces the Go programming as a dependency and has non-optimal or missing version pinning. -- 1. https://github.com/reproducible-containers/diffoci

Build on 7fea392 by using the `--no-cache` option to prevent the container build from re-using any build cache in order to realistically create two distinct builds to be tested for reproducibility.
