Some of XDP samples that are attaching the bpf program to the interface
via libbpf's bpf_set_link_xdp_fd are still using the bpf_load.c for
loading and manipulating the ebpf program and maps. Convert them to do
this through libbpf usage and remove bpf_load from the picture.

While at it remove what looks like debug leftover in
xdp_redirect_map_user.c

xdp_redirect_cpu is omitted because of read_trace_pipe() usage, which
doesn't seem to be handled in libbpf ATM.

Thanks a lot for converting sample/bpf programs to use libbpf.  It have
been on my todo list for a very long time.
