box gadget: Fix baseline allocation for widgets
We were adjusting the allocation to line up baselines before calling gtk_widget_size_allocate_with_baseline, but that function is doing this alignment internally anyway and expects to be given a 'fill' allocation. Move the allocation adjustment code down into gtk_box_gadget_allocate_child where it only affects child gadgets, not child widgets.
