Zuul jobs are running out of space and failing. This attempts to
resolve by cleaning up between the build/publish of each image.
Switched to the ansible command module, since the make module doesn't
support multiple make targets.
Added a clean target to any image which didn't already have one, which
was just the ipa-downloader-image.
