Subject: [PATCH bpf-next 6/8] libbpf: Recognize SK_REUSEPORT programs from section name

Allow loading BPF object files that contain SK_REUSEPORT programs without
having to manually set the program type before load if the the section name
is set to "sk_reuseport".

Makes user-space code needed to load SK_REUSEPORT BPF program more concise.
