bpftool: Show target_{obj,btf}_id in tracing link info
The target_btf_id can help us understand which kernel function is
linked by a tracing prog. The target_btf_id and target_obj_id have
already been exposed to userspace, so we just need to show them.
The result as follows,
$ tools/bpf/bpftool/bpftool link show
2: tracing prog 13
prog_type tracing attach_type trace_fentry
target_obj_id 1 target_btf_id 13964
pids trace(10673)
$ tools/bpf/bpftool/bpftool link show -j
[{"id":2,"type":"tracing","prog_id":13,"prog_type":"tracing","attach_type":"trace_fentry","target_obj_id":1,"target_btf_id":13964,"pids":[{"pid":10673,"comm":"trace"}]}]
