Don't add duplicated line box rects into focus ring rects

Don't add duplicated line box rects into focus ring rects

LayoutBlock::addFocusRingRects() adds root line box rects;
LayoutInline::addFocusRingRects() adds its line box rects, but
this is unnecessary if the parent has added root line box rects or
normal line box rects.

This might be the reason of OOM during addFocusRingRects.
