[PATCH bpf-next 6/6] libbpf: Use __u32 instead of u32 in bpf_program__load

[Andrey Ignatov]

Make bpf_program__load consistent with other interfaces: use __u32
instead of u32. That in turn fixes build of samples:

In file included from ./samples/bpf/trace_output_user.c:21:0:
./tools/lib/bpf/libbpf.h:132:9: error: unknown type name ‘u32’
         u32 kern_version);
         ^

Fixes: commit 29cd77f41620d ("libbpf: Support loading individual progs")
