Fix the wrong measure for the change in ExplainState.

The fix made in the commit 6819c84350ea599988440c5c07becfe56c71723a is
not appropriate according to its objective. The correct fix for the
change is translating es->extra as "List *grouping_stack" in the
versions 9.3.6, 9.4.1 and their successors. This secure the binary
comaptibility throughout minor PG versions.
