selftests/bpf: Use bpf_check_mtu in selftest test_cls_redirect
This demonstrate how bpf_check_mtu() helper can easily be used together
with bpf_skb_adjust_room() helper, prior to doing size adjustment, as
delta argument is already setup.
Hint: This specific test can be selected like this:
./test_progs -t cls_redirect
