samples: bpf: Replace sizeof(arr)/sizeof(arr[0]) with ARRAY_SIZE
The ARRAY_SIZE macro is more compact and more formal in linux source. Signed-off-by: Linkui Xiao <xiaolinkui@kylinos.cn> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Jiri Olsa <jolsa@kernel.org> Link: https://lore.kernel.org/bpf/20220712072302.13761-1-xiaolinkui@kylinos.cn
