Add a "bpf_util.h" include to avoid the following error seen compiling for mips64el with musl libc:

I'm curious why this error doesn't occur on other platforms. ARRAY_SIZE is actually defined in linux/kernel.h (tools/include/linux/kernel.h). I think you should find out why this file is not included on your platform.
