tests: Change handling of reading non blocked empty stream for python3
The result of reading non blocked empty stream is different between python2 and 3. The python2 sends "[Errno 11] Resource temporarily unavailable" exception. The python3 could read "None" without exception, so handle this "None" case as well. Signed-off-by: Masashi Honma <masashi.honma@gmail.com>
