Use GL_NEAREST filter in the draw-and-read get_data texture fallback
Use GL_NEAREST filter in the draw-and-read get_data texture fallback

The fallback for when glGetTexImage is not available renders the
texture to the framebuffer to read the data using glReadPixels. This
patch just sets the COGL_MATERIAL_FILTER_NEAREST filter mode on the
material before rendering to avoid linear filtering which would alter
the texture data.
