android: do not expose single buffered eglconfigs

Browse source 
On Android we want to add only double buffered configs for visuals.
Earlier implementation set the SurfaceType as 0 for single buffered
configs but driver still exposed these configs that were not compatible
with any egl surface type.  This caused Khronos conformance test runs to
fail on Android. This patch fixes the issue by skipping single buffered
configs earlier and not exposing them.
