vkd3d-shader/spirv: Shift the private variable destination mask instead of the source mask.

Browse Source 
Otherwise if the input is located above position 0 in the private array
it will be swizzled incorrectly, e.g. a.yz instead of a.xy in
test_domain_shader_inputs().

Based on a vkd3d-proton patch by Hans-Kristian Arntzen.
