obsutil: fix the issue5686

While traversing the obsolescence graph to find the successors sets
of csets:
    In its 4th case (read comments of obsutil.successorssets to see
    all 4 cases) where we know successors sets of all direct successors
    of CURRENT, we were just missing a condition to filter out the case
    when a cset is pruned.
    And without this condition (that this patch added) it was making a whole
    successor set to [] just because of one pruned marker.

For e.g:if following is the successors set of a cset A:
           A -> [a, b, c]

        if we prune c, we expect A's successors set to be [a, b] but
        you would get:
           A -> []
So this patch make sure that we calculate the right successorsset of csets
considering the pruned cset (in split case).
