tools: bpftool: add owner_prog_type and owner_jited to bpftool output
For prog array maps, the type of the owner program, and the JIT-ed state of that program, are available from the file descriptor information under /proc. Add them to "bpftool map show" output. Example output: # bpftool map show 158225: prog_array name jmp_table flags 0x0 key 4B value 4B max_entries 8 memlock 4096B owner_prog_type flow_dissector owner jited # bpftool --json --pretty map show [{ "id": 1337, "type": "prog_array", "name": "jmp_table", "flags": 0, "bytes_key": 4, "bytes_value": 4, "max_entries": 8, "bytes_memlock": 4096, "owner_prog_type": "flow_dissector", "owner_jited": true } ] As we move the table used for associating names to program types, complete it with the missing types (lwt_seg6local and sk_reuseport). Also add missing types to the help message for "bpftool prog" (sk_reuseport and flow_dissector).
