Subject: [PATCH] tests: ceph.spec.in or debian/control rebuild docker images

If any of the files in test/$os_type is newer than the creation date of
a docker image, the image is removed and rebuilt from scratch. For
instance, when a package is added to debian/control, the debian based
images are rebuilt.
