Splitting scrollbars into multiple fragmentainers is only problematic
in interactive media.
We don't need to impose any such pagination restrictions when
printing, since printing is non-interactive.

* Source/WebCore/rendering/RenderBox.cpp:
(RenderBox::hasUnsplittableScrollingOverflow): As above
* LayoutTests/printing/overflow-auto.html: Add Test Case (with pixel tolerance)
* LayoutTests/printing/overflow-auto-expected.html: Add Test Case Expectation
