Kui-Feng Lee e51cdaaca0 libbpf: Update a bpf_link with another struct_ops. ...

Introduce bpf_link__update_map(), which allows to atomically update
underlying struct_ops implementation for given struct_ops BPF link.

Also add old_map_fd to struct bpf_link_update_opts to handle
BPF_F_REPLACE feature.
