Fix ForeverStack::find_starting_point output parameter

gcc/rust/ChangeLog: * resolve/rust-forever-stack.h (ForeverStack::find_starting_point): Use type 'std::reference_wrapper<Node> &' instead of 'Node &' for parameter starting_point. * resolve/rust-forever-stack.hxx (ForeverStack::find_starting_point): Likewise. (ForeverStack::resolve_path): Handle change to ForeverStack::find_starting_point. Signed-off-by: Owen Avery <[email protected]>
