Remove network bypass flags for non-connectivity jobs.

If a job doesn't say that it needs network, then there's no reason to
ensure that the app has access to network while the job is running.
Currently, the network restriction bypass flags are only given to
expedited or user-initiated jobs. Don't include the flags when the job
doesn't require connectivity to avoid accidental network usage/leakage.
