panfrost: Stub out set_shader_images().

If PAN_MESA_DEBUG=deqp is set to enable testing, then we advertise shader
images to get GLES3.1, even though we don't have any of the shader image
funcs hooked up.  This caused breakage when cso started unbinding shader
images at context destruction.

Just stub out the function for now, you'll still segfault when creating an
image.
