revset: use direct access to __contains__ in spanset.__sub__

Using `x.__contains__(r)` instead of `r in x` does not matter for built-in type
(set) but have a positive impact for all other classes. This will let us drop
some usage of baseset.set() in future patches. This also probably improves some
performance.
