timerfd_settime02 from ubuntu_ltp_syscalls failed on B s390x

[Po-Hsu Lin]

This issue was only found on s390x nodes, the test failed with:
    tst_taint.c:88: BROK: Kernel is already tainted: 12800

Looks like this was caused by something else in this test suite.

And this is a new test case, we don't have it for the last cycle (4.15.0-91.92), thus this is not a regression.

Test output on 4.15.0-92 s390x:

Looks like this was caused by add_key01 test (bug 1862878), which failed before this one.

After reviewing the bug, it appears that this is not a critical failure. The test case needs to be triaged and reviewed, as we have prior failures.
