Avoid using ThreadList::Dump() in empty checkpoint timeout.

ThreadList::Dump() that uses a checkpoint to dump threads may get
stuck when an empty checkpoint gets stuck and isn't useful when
debugging an empty checkpoint timeout. Instead, directly use
Thread::Dump() for each runnable thread that isn't responding to an
empty checkpoint request.
