[PATCH bpf-next 4/4] bpftool: Show also the name of type BPF_OBJ_LINK

For example,
/sys/fs/bpf/maps.debug is a bpf link, when you run `bpftool map show` to
show it,
- before
$ bpftool map show pinned /sys/fs/bpf/maps.debug
Error: incorrect object type: unknown
- after
$ bpftool map show pinned /sys/fs/bpf/maps.debug
Error: incorrect object type: link
