Improve `OS.{Dir,Path}.delete ~recurse:true` reliability.

W.r.t. races, see https://github.com/dbuenzli/bos/issues/50#issuecomment-223592710 and discussion in #50.

The problem is that we [simply](https://github.com/dbuenzli/bos/blob/master/src/bos_os_path.ml#L446) `Fpath.normalize` the initially provided paths and consult its basename. Of course this won't work e.g. if the directory pointed by an initial path like...

Windows needs to know whether you link to a directory or a file. See https://github.com/ocaml/ocaml/pull/462

Make `OS.Dir.delete ~recurse:true` secure to symlink attacks.
