landlock07 from ubuntu_ltp_syscalls failed on Noble

[Po-Hsu Lin]

This is a new test case added on Aug. 22
https://github.com/linux-test-project/ltp/commit/dc8e343ec1a57485e29a28beb82b50667d6147de

And we got our fork updated recently in order to cover Oracular.
So this is not a regression.

Test failed with:
  landlock07.c:66: TFAIL: open("/dev/null", O_WRONLY) invalid retval 4: SUCCESS (0)
