[Piglit] [PATCH 3/3] cs: Use GL_RGBA8 for image_load_store internal format

[Jordan Justen]

The motivation for this is that (as noted by curro)
ARB_shader_image_load_store doesn't support images with an internal
format of GL_RGBA.

See 'Table X.2' in
https://www.opengl.org/registry/specs/ARB/shader_image_load_store.txt

Therefore, in order to use image load/store in shader runner tests, we
must override the default internal format when creating the image.
