Akihiro Suda	6322dfc217	archive: do not use overlayWhiteoutConverter for UserNS ... overlay2 no longer sets `archive.OverlayWhiteoutFormat` when running in UserNS, so we can remove the complicated logic in the archive package.

Akihiro Suda	f8ed19c8b4	pkg/archive: support overlayfs in userns (Ubuntu kernel only) ... Ubuntu kernel supports overlayfs in user namespaces. However, Docker had previously crafting overlay opaques directly using mknod(2) and setxattr(2), which are not supported in userns. Tested with LXD, Ubuntu 18.04, kernel 4.15.0-36-generic #39-Ubuntu.
