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.
