Fix AppArmor test at scale

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

The AppArmor test only runs on a single node, but previously was loading the necessary profiles to every node. This caused unnecessary churn in very large clusters, so this PR updates the test to only load the profiles to a single node, and ensure the test pod is run on that node (using pod affinity).

**Which issue this PR fixes**: fixes #51791
