The localname from topology.blobstore.map reached new File(root, name) unnormalised in both AsyncLocalizer and Container.createBlobstoreLinks, and createSymlink force-deletes whatever already exists at the target.

Both sites now require the resolved target to be inside the expected root. Extends AsyncLocalizerTest and ContainerTest.
