oox smartart, cycle matrix: fix fill and line props of shape

The topmost shape may not have 0 depth, but something larger.

In that case at least it's safe to still use fill & line properties. The
B1 quadrant of the test file now has the proper orange background, and
B2's border is also properly orange.
