iOS: Don't enable kEAGLDrawablePropertyRetainedBacking

Browse Source 
We report our swap-behavior as QSurfaceFormat::DoubleBuffer, which means
there's no point in using retained backing. This was a left-over from
when we reported single-buffered swaps, which didn't work to well as
clients would wrongly assume swap was not needed at all.
