Enforce privileged PSA by default

[Evan-Reilly]

What this PR does / why we need it:
OpenShiftPodSecurityAdmission feature gate is not enabled by default in 4.17 any longer: https://github.com/openshift/api/blob/release-4.17/features/features.go, openshift/api#2018. Therefore, to ensure namespace security is not enforcing restricted by default any longer, this PR is required to properly enforce privileged PSA by default.

Which issue(s) this PR fixes (optional, use fixes #<issue_number>(, fixes #<issue_number>, ...) format, where issue_number might be a GitHub issue, or a Jira story:

Hi @Evan-Reilly. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
