Thanks for the review!

Actually, I'm well aware that there are some samples left with old style map
definitions, But those examples should be transferred from bpf_load to
libbbpf, not just bpf map changes.

I'm also planning to refactor those patches in the future.
For now I've just refactored this file, but if you think this patch
size is small,
I'll send it with other changes.
