selftests/bpf: Fix missing ARRAY_SIZE() definition in bench.c

Browse Source 
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
