Daniel Borkmann 82bbe13331 selftests/bpf: Add test for passing in uninit mtu_len

Add a small test to pass an uninitialized mtu_len to the bpf_check_mtu()
helper to probe whether the verifier rejects it under !CAP_PERFMON.

  # ./vmtest.sh -- ./test_progs -t verifier_mtu
  [...]
  ./test_progs -t verifier_mtu
