It is useful to print map ID on successful creation.

JSON case: $ ./bpftool -j map create /sys/fs/bpf/test_map4 type hash key 4 value 8 entries 128 name map4 {"id":12}

Generic case: $ ./bpftool map create /sys/fs/bpf/test_map5 type hash key 4 value 8 entries 128 name map5 Map successfully created with ID: 15
