bpf: Show target_{obj,btf}_id in tracing link fdinfo
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,
$ cat /proc/10673/fdinfo/10
pos: 0
flags: 02000000
mnt_id: 15
ino: 2094
link_type: tracing
link_id: 2
prog_tag: a04f5eef06a7f555
prog_id: 13
attach_type: 24
target_obj_id: 1
target_btf_id: 13964
