landlock04 from ubuntu_ltp_syscalls failed on Jammy (TBROK: landlock_add_rule)

[Po-Hsu Lin]

This is a new test case added on Aug. 8
https://github.com/linux-test-project/ltp/commit/0e19ce15690055231fe4954e8b3711a3a47c937a

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

Test failed with:
  TBROK: landlock_add_rule(8, 1, 0xfffd3c6ffff4, 0): EINVAL (22)

On all 7 testable filesystems in the end of the test.
