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
