Use Any instead of object in the view types for __and__ and __sub__ (#3294)

Browse Source 
This was discussed in #3181 and the correct explanation was given that
object ought to be preferred here. In practice this caused an obscure
issue with mypy when using this operations on the results of
six.viewkeys(), since it decided that it wanted a mapping *from* object
as a result of inference contexts. Grumble.
