Make EGL surface transparency working on Symbian.
When the hardware is capable enough, setting WA_TranslucentBackground
will not lead to falling back to raster, but will continue using
OpenVG or OpenGL based rendering. However this needs an alpha channel
which was not requested previously. This patch corrects it.
Task-number: QT-4729
