emit_obj_refs_json needs to added the same as with emit_obj_refs_plain
to prevent segfaults, similar to Commit "8ae4121bd89e bpf: Fix bpftool
without skeleton code enabled"). See the error below:

     # ./bpftool -p prog
     {
         "error": "bpftool built without PID iterator support"
     },[{

The same happens for ./bpftool -p map, as well as ./bpftool -j prog/map.

Fixes: d53dee3fe013 ("tools/bpftool: Show info for processes holding BPF
