cherrpy port should depend on more-itertools

[vkuznet (Valentin Kuznetsov)]

The cherrpy package (tested in Python 2.7) should depend on more-itertools. Here is the chain of failed dependency:

Once I installed manually more-intertools everything comeback to normal

Looks more like it's py27-jaraco.functools that needs the dependency. Although there's a lot going on here: cherrypy is importing portend but doesn't appear to depend on it, and tempora is importing jaraco.functools but doesn't appear to depend on it.
