adoptopenjdk:8-*-hotspot on arm32v7 is missing libatomic.so.1

[Tianon Gravi]

(See also #458 -- this is roughly the same issue, but a different library and a different architecture...)

I think this would be easier to catch if the Dockerfile were updated to also include java -version after Java is downloaded (and I'd recommend adding javac -version on JDK images too).

Concretely, the suggested delta to https://github.com/AdoptOpenJDK/openjdk-docker/blob/e637c8ff34bb4ca7bc14826aaf8bbcc580d5e586/8/jdk/ubuntu/Dockerfile.hotspot.releases.full would be:

(That way, the images would only even be published if java is able to run and report its version successfully, instead of catching this in downstream image builds that then fail to run Java.)

FWIW, this PR to official-images created usable arm32v7 images: docker-library/official-images#8918; While this one did not: docker-library/official-images#9063.

Can I grab this? I've got a PR up for it.
