bpf: Fix another bpftool segfault without skeleton code enabled
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"

Segmentation fault (core dumped)
The same happens for ./bpftool -p map, as well as ./bpftool -j prog/map.
