Yep, rivets, no screws or glue.
You could use a small screw with two nuts to make a foot. Run the screw through the hole with a bolt (plus washer?) on each side.Adjust for right height and tighten. Probably safest to put some black electrical tape or some other light seal material on the inside.
A missing foot is a light leak more than anything. If the camera sitting on its feet isn't required, simply seal up the hole.
