Jakub Sitnicki e948947a6e bpftool: Support link show for netns-attached links
Make `bpf link show` aware of new link type, that is links attached to
netns. When listing netns-attached links, display netns inode number as its
identifier and link attach type.

Sample session:

  # readlink /proc/self/ns/net
  net:[4026532251]
  # bpftool prog show
  357: flow_dissector  tag a04f5eef06a7f555  gpl
          loaded_at 2020-05-30T16:53:51+0200  uid 0
          xlated 16B  jited 37B  memlock 4096B
  358: flow_dissector  tag a04f5eef06a7f555  gpl
          loaded_at 2020-05-30T16:53:51+0200  uid 0
          xlated 16B  jited 37B  memlock 4096B
  # bpftool link show
  108: netns  prog 357
          netns_ino 4026532251  attach_type flow_dissector
  # bpftool link -jp show
  [{
          "id": 108,
          "type": "netns",
          "prog_id": 357,
          "netns_ino": 4026532251,
          "attach_type": "flow_dissector"
      }
  ]

  (... after netns is gone ...)

  # bpftool link show
  108: netns  prog 357
          netns_ino 0  attach_type flow_dissector
  # bpftool link -jp show
  [{
          "id": 108,
          "type": "netns",
          "prog_id": 357,
          "netns_ino": 0,
          "attach_type": "flow_dissector"
      }
  ]
