glsl: Fix the foreach_in_list_reverse macro.

We clearly don't want to start at the head and walk backwards; we want
to start at the last real element before the tail sentinel.  If the list
is empty, tail_pred will be the head sentinel, and we'll stop.

Nothing uses this function, so I guess nobody noticed it was broken.
