cogl_read_pixels: Fix the format used in GLES2
When converting the data in cogl_read_pixels it was using bmp_format instead of the format passed in to the function. bmp_format is the same as the passed in format except that it always has the premult bit set. Therefore the conversion would not handle premultiply correctly. http://bugzilla.clutter-project.org/show_bug.cgi?id=2414
