Blacklist some spurious failures

I don't know if these qualify as spurious failure, but the following two regressions showed up in a  report recently and (as far as I can tell) do not have anything to do with the actual change:

* https://crater-reports.s3.amazonaws.com/pr-71814/try%235fae8f15a4dcfce640ee800a4d495673524b0a4d/gh/luc-tielen.fire-emblem-rs/log.txt
* https://crater-reports.s3.amazonaws.com/pr-71814/try%235fae8f15a4dcfce640ee800a4d495673524b0a4d/reg/xtp-0.1.0-alpha.4/log.txt

The error in both cases is `sudo: setrlimit(RLIMIT_CORE): Operation not permitted`. Why that is a regression (i.e. why the "reference run" worked and only the changed run failed) I have no idea...
