Use ARRAY_SIZE() because it uses __must_be_array(arr) to make sure arr is really an array.

No need for the extra include. test_progs.h already includes bpf_util.h, please check such trivialities before submission. Simple grep would have revealed use of ARRAY_SIZE() in various places under tools/testing/selftests/bpf/prog_tests/.

There are many more similar occurrences. Please just send one cleanup patch to reduce churn in the git log.
