cool#7015 fix rgba emojis
We initially added this for android so we could match the OpenGL GL_RGBA
layout available there. Later we made it available for all platforms via
--enable-cairo-rgba which is useful for the kit case.
But along the line color emoji support was added to cairo which wasn't
present at the time of the original patch, so now capture those uses
as well.
