Title: Skip some Windows io failures

It appears that if stdout is redirected, writes that go through `IPython.utils.io.stdout` don't work on Windows. We need to clear up our standard stream references (#14), but for now I'm silencing a couple of test failures (#4906, #4907) so we can see more serious problems on Windows.
