Mark RESTRICTED bucket stop reasons.

Try to mark when a job is being stopped because it's in the RESTRICTED
bucket. Even though the job's requested constraints may become
unsatisfied around the same time as dynamic constraints, this just
assumes that any unsatisfied dynamic constraints are the reason the job
is being stopped.
