tools: libbpf: add a correctly named define for map iteration
For historical reasons the helper to loop over maps in an object is called bpf_map__for_each while it really should be called bpf_object__for_each_map. Rename and add a correctly named define for backward compatibility. Switch all in-tree users to the correct name (Quentin).
