Automatic merge from submit-queue (batch tested with PRs 66196, 67016, 66807, 67023). If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>.

e2e: Ensure that sysrq-trigger is enabled before use

**What this PR does / why we need it**:

On Ubuntu (and, presumably, other distros too), the default configuration prohibits some sysrq operations.  Before performing sysrq operations in the e2e testing, ensure that all operations are permitted.
