Filter driveway zone to person/dog/cat only in Frigate

Parked car was being re-detected every few minutes at night due to IR
illumination noise triggering motion detection. Restrict the driveway
zone to [person, dog, cat] so cars and birds no longer create events
there. Cars still alert via the driveway_entrance zone.
