Redoing the previously failed fix. The earlier fix unnecessarily added all metazones to the root bundle, even when the names were empty. The revised fix updates metazone names only when the mapped zone has its own names (which fixes the original backporting issue, and is not applicable to the current mainline). I confirmed that the resource bundles generated by CLDRConverter are identical to those from the baseline build without this fix.
