rtcpie in timers from ubuntu_kernel_selftests randomly failing

Also seeing this on B/hwe-5.4 5.4.0-75.84~18.04.1, though looks like a flaky test.

I've hit this in bionic/linux-hwe-5.4(2023.01.30, kopter host).

We have looked a bit deeper both into the test itself but also looking for how other "people" manage this. I'm not going to echo much as I think that this comment (https://bugs.linaro.org/show_bug.cgi?id=3402#c9) from Linaro nicely describes both the problem and how this is an unreasonably unstable test. Upstream was contacted for a tolerance increase in the test but no feedback was received (https://<email address hidden>/).

We have been dragging this test for a good while blocked in a hinting-loop to ignore the results of this test which is costing us time to no benefits at all. I propose and will go ahead with patch ml submissions to avoid failing the test even if the 10% threshold is passed. I propose to go with this as opposed to a full revert of 0b63accf87225b5eb7e52814c374cf02d733d4bb for the following reasons:
1. it keeps running the test with results and data that we can use in the future for any "smarter" way to deal with it - eg. statistically
2. it minimizes the maintenance burden of that patch kept in our kernel trees (a simple exit line removal)

As mentioned above, the test was added through upstream 0b63accf87225b5eb7e52814c374cf. This was included from 4.1 onwards thus making most of our supported trees affected (except for Trusty):

* Lunar, Lunar unstable, Kinetic, Jammy (including OEM 5.17, 6.0 and 6.1), Focal (including oem 5.14) - patch sent to the mailing list: https://lists.ubuntu.com/archives/kernel-team/2023-February/137224.html
* Bionic and Xenial - patch sent to the mailing list https://lists.ubuntu.com/archives/kernel-team/2023-February/137222.html

To avoid retriggering testing on Bionic/linux-oem-5.4-144, I have also proposed an rt hint for this specific release cycle: https://code.launchpad.net/~canonical-kernel-team/+git/rt-hints/+merge/437570

I try to change the package to the main kernel one since we apply it there.

Also adjusted the title since that appears in each changelog and would be somewhat confusing.
