[PATCH bpf-next v1 07/19] selftests/bpf: Fix missing ARRAY_SIZE() definition in bench.c

[Tony Ambardar <tony.ambardar@xxxxxxxxx>]

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

  bench.c: In function 'find_benchmark':
  bench.c:590:25: error: implicit declaration of function 'ARRAY_SIZE' [-Werror=implicit-function-declaration]
    590 |         for (i = 0; i < ARRAY_SIZE(benchs); i++) {
        |                         ^~~~~~~~~~
  cc1: all warnings being treated as errors

Fixes: 8e7c2a023ac0 ("selftests/bpf: Add benchmark runner infrastructure")
