rust: sync: implement == operator for ARef

Rust Binder wants to perform a comparison between ARef<Task> and &Task,
so define the == operator for ARef<_> when compared with another ARef<_>
or just a reference. The operator is implemented in terms of the same
operator applied to the inner type.

Note that PartialEq<U> cannot be implemented because it would overlap
with the impl for ARef<U>.
