Message:

On iOS, we never want to make scrollbar layers
​https://bugs.webkit.org/show_bug.cgi?id=127024
<rdar://problem/15745768>

Reviewed by Dean Jackson.

On platforms that delegate scrolling, don't try to make layers
for scrollbars.

This fixes a crash in RenderLayerCompositor::updateOverflowControlsLayers()
where m_overflowControlsHostLayer is null.
