Fixes kubectl cached discovery on Windows

Fixes https://github.com/kubernetes/kubectl/issues/18

The `kubectl` cached discovery makes use of `func (f *File) Chmod(mode FileMode) error` which is not supported and errors out on Windows, making `kubectl get` and potentially a number of other commands to fail miserably on that platform. `os.Chmod` by file name, on the other hand, does not error out and should be used instead.

**Release note**:
