samples: bpf: Refactor xdp_monitor with libbpf
To avoid confusion caused by the increasing fragmentation of the BPF Loader program, this commit would like to change to the libbpf loader instead of using the bpf_load. Thanks to libbpf's bpf_link interface, managing the tracepoint BPF program is much easier. bpf_program__attach_tracepoint manages the enable of tracepoint event and attach of BPF programs to it with a single interface bpf_link, so there is no need to manage event_fd and prog_fd separately. This commit refactors xdp_monitor with using this libbpf API, and the bpf_load is removed and migrated to libbpf. Signed-off-by: Daniel T.
