bpf: Fix bpftool without skeleton code enabled
Fix segfault from bpftool by adding emit_obj_refs_plain when skeleton
code is disabled.
Tested by deleting BUILD_BPF_SKELS in Makefile. We found this doing
backports for Cilium when a testing image pulled in latest bpf-next
bpftool, but kept using an older clang-7.
# ./bpftool prog show
Error: bpftool built without PID iterator support
