manifest: make intersectfiles() private

Since 0cc283f44655 (manifest: add matches() method, 2014-10-22), the
intersectfiles() method has been an implementation detail. The
treemanifest class will probably want to special-case differently and
should not have to provide intersectfiles() for API compatibility with
manifestdict(). For now, let's add a '_' prefix to indicate that it's
not part of the API.
