mesa/program: fix shadow property for samplers

When creating a sampler-type, we need to pass the correct vaclue for
the "is_shadow"-parameter to glsl_sampler_type(), otherwise the compiler
backend will have no clue about this being a shadow-sampler.

Fixes: 1c0f92d8a8c ("nir: Create sampler variables in prog_to_nir.")
