jobqueue: return dependencies on dequeue

Browse source 
Once a job has been enqueued, there is no way to query its dependencies.

This makes dequeue more symmetric to enqueue by returning the
dependencies that were passed to enqueue, allowing the caller to
query the dependencies and their results.
