sparse: implement negatematcher.visitdir
Summary: `negatematcher.visitdir` was using the default implementation - `return True`. It's correct but not helpful to skip visiting a large directory. Make it return more efficient results if possible. Reviewed By: DurhamG Differential Revision: D10352848 fbshipit-source-id: 05b19342192a54e114d02564058435fb3ac34590
