bpftool: Support struct_ops, tracing, ext prog types
Add support for prog types that were added to kernel but not present in
bpftool yet: struct_ops, tracing, ext prog types and corresponding
section names.
Before:
# bpftool p l
...
184: type 26 name test_subprog3 tag dda135a7dc0daf54 gpl
loaded_at 2020-02-25T13:28:33-0800 uid 0
xlated 112B jited 103B memlock 4096B map_ids 136
btf_id 85
185: type 28 name new_get_skb_len tag d2de5b87d8e5dc49 gpl
loaded_at 2020-02-25T13:28:33-0800 uid 0
xlated 72B jited 69B memlock 4096B map_ids 136
btf_id 85
After:
# bpftool p l
...
184: tracing name test_subprog3 tag dda135a7dc0daf54 gpl
loaded_at 2020-02-25T13:28:33-0800 uid 0
