jobs: respect server queiscing in maybeDumpTrace

Previously, we ignored the context cancellation function in
`maybeDumpTrace` that is returned by `makeCtx`, which made it so that we
could stuck indefinitely on the server shutdown. We now include the
cancellation function to be called on Queisce.

Release note: None
