treemanifest: add treemanifest._isempty()
During operations that involve building up a new manifest tree, it will be
useful to be able to quickly check if a submanifest is empty, and if so, to
avoid including it in the final tree. Doing this check lets us avoid creating
treemanifest structures that contain any empty submanifests.
