zink: do not ask glsl-compiler to unroll

Browse source 
We don't really need loops unrolled, so let's just disable this. This is
generally recommended for NIR drivers, but we can do even better; not
even unroll in NIR. And since we don't set
nir_shader_compiler_options::max_unroll_iterations, we're already there.
