i965: Fix GS push inputs with enhanced layouts.
We weren't taking first_component into account when handling GS push
inputs. We hardly ever push GS inputs, so this was not caught by
existing tests. When I started using component qualifiers for the
gl_ClipDistance arrays, glsl-1.50-transform-feedback-type-and-size
started catching this.
