Introduces an intermediate format for overlayfs storage, where .wh-ostree. prefixed files will be converted into char 0:0 whiteout devices used by overlayfs to mark deletions across layers. The CI scripts now uses a volume for the scratch directories previously in /var/tmp otherwise we cannot create whiteout devices into an overlayfs mounted filesystem. Related-Issue: #2712
