Refs #1048
Add a dev script for Linux platforms that verifies that a source image
can be reproducibly built from the current Git commit. The
reproducibility check is enforced by the `diffoci` tool, which is
downloaded as part of running the script.
Allow setting a tag for the container image, when building it with the
`build-image.py` script. This should be used for development purposes
only, since the proper image name should be dictated by the script.
