arb_texture_cube_map_array: sample-cube-map-array-shadow don't mix piglit_draw_rect and custom attribute arrays

The problem is that my patch swapped the drawing order of the vertices which causes problems for tests that use piglit_draw_rect* with additional attribute arrays.
I'll also post this patch along with similar ones for glsl-max-varyings, copyteximage and sampler-cube-shadow to the list.
