Fix last DRC incorrect case in TrackSegment::isMiddleStack(). 

* Bug: In TrackSegment::isMiddleStack(), formerly, all global segments
    where discarted. But in the routing repair stage, segments can go
    *outside* their GCell boundaries, allowing globals to became of
    null length.
       Hence, for global, we now also check the wirelength.
