_split_token(): handle None
The conditional + list comprehension in images.py:_split_token()
wasn't quite working as intended; in particular, when fed None,
it chokes with
TypeError: 'NoneType' object is not iterable
This is the correct behavior: comprehensions iterate first,
then apply the conditional.
Solution: special-case None, and remove the now-unnecessary
conditional.
Context: seen when trying 'pypodman run' against
docker.io/stackbrew/centos:7, which has no .ContainerConfig.Eng
