Add a dummy Store::buildPaths() method
This default implementation of buildPaths() does nothing if all requested paths are already valid, and throws an "unsupported operation" error otherwise. This fixes a regression introduced by c30330df6f67c81986dfb124631bc756c8e58c0d in binary cache and legacy SSH stores.
