Frederik Gladhorn f3e86a8cc8 Accessibility Linux: Fix methods returning rects as iiii for AT-SPI 
According to the spec rects get returned with iiii but we were directly
serializing QRect resulting in (iiii) as signature.
This would trip up Orca when trying to use flat review in text edits.

Task-number: QTBUG-39702
