qpa: Fix rendering issue in blitter engine (negative scaling factors)

A 180° rotation results in a TxScale QTransform with negative scaling
factors (x=-1.0 y=-1.0). This is not properly handled by blitter paint
engine yet, so use software rendering fallback in this case.

This rendering issue can be seen when using "-webkit-transform" CSS
property in WebKit with DirectFB QPA platform.
