core/service: use common implementation of unit_load_fragment_and_dropin()

There is a slight functional change when load_state == UNIT_MERGED. Before,
we would not call unit_load_dropin(), but now we do. I'm not sure if this
causes an actual difference in behaviour, but since all other unit types do
this, I think it's better to do the same thing here too.
