test: Fix cleanup after PolicyAuditMode test

This test set the PolicyAuditMode, but didn't revert it afterwards. This
meant that subsequent tests could potentially fail because they didn't
expect this setting to be configured.

Fix it by adding an AfterAll() that turns the feature back off.

Fixes: 6cd69ed ("Implement policy audit mode for the daemon")
Fixes: #10486
