But it wasn't really doing anything. Because adding the image to
DOCKER_DEPRECATED_IMAGES had the same effect as using
DOCKER_PARTIAL_IMAGES. You couldn't invoke the test from make and it was
dropped out from the dependencies for the do-X-on-all image rules. As it
was also hidden from the help you might as well just delete the thing
all together.

I think deprecations are better handled by a noisy warning in the
dockerfile than the silent suppression of their existence by the make
system.
