tools/bpf: support __int128 in bpftool map pretty dumper ...
For formatted output, currently when json is enabled, the decimal
number is required. Similar to kernel bpffs printout,
for int128 numbers, only hex numbers are dumped, which are
quoted as strings.
The below is an example to show plain and json pretty print
based on the map in test_btf pretty print test.
$ bpftool m s
75: hash name pprint_test_has flags 0x0
key 4B value 112B max_entries 4 memlock 4096B
