treemanifest: disable readdelta optimization
When tree manifests are stored with one revlog per directory and
loaded lazily, it's unclear how much readdelta will help. If only a
few files change, then only a small part of the full manifest will be
loaded, and the delta chains should also be shorter for tree
manifests. Therefore, let's disable readdelta for tree manifests for
now.
