D2G: several tasks seem to need --privileged flag passed to podman run

[petemoore]

There appear to be an increasing number of tasks that ran under docker-worker without privileged capability that are not running successfully under podman without --privileged flag. Since for podman, "privileged" doesn't increase privileges of task, it just increases the privileges inside the container that the task user already has outside the container, let's just pass --privileged regardless. This should more closely match the privileges that the docker worker tasks have.

Examples:

• Bugmon monitor tasks (fuzzing)
  • Issue #6888
  • Task: https://community-tc.services.mozilla.com/tasks/evzR-_XzS0mKjTDanC8G0g
• Loopback video task
  • No issue
