update_engine: UM: Change policy argument from const ref to value.
It turns out that passing an argument by reference to UpdateCanStart via
UpdateManager::AsyncPolicyRequest is a pain. Furthermore, given that the
policy is async by definition, it makes little sense to hand it a const
reference argument. This changes the said argument to be passed by
value.
