rust: regulator: implement Send and Sync for Regulator<T>
Sending a &Regulator<T> to another thread is safe, as the regulator core
will properly handle the locking for us. Additionally, there are no
restrictions that prevents sending a Regulator<T> to another thread.
Given these two facts, implement Send and Sync.
