Recently we added reporting package-level failures (that is not associated to a specific test) to LUCI. In some cases, e.g. at timeout, LUCI reports both test failures and package-level failures. E.g. https://ci.chromium.org/ui/p/golang/builders/ci/gotip-netbsd-arm64/b8745232168515795905/overview, which has failures for both os/exec.TestCancelErrors/killed_after_error and os/exec. Currently watchflakes reports two issues for them, in this case #68436 and #66895. We should not report the package-level one.
