[JimBugwadia]

Fixes #1332.

---

Fixed handling of anchors and wildcards in patterns:

kubectl-kyverno.exe apply C:\Users\jbugwadia\Code\go\src\github.com\kyverno\policies\pod-security\default\restrict-apparmor-profiles.yaml  -r C:\Users\jbugwadia\Code\go\src\github.com\kyverno\policies\pod-security\tests\default\test-restrict-apparmor-profiles.yaml

applying 1 policy to 1 resource...

policy restrict-apparmor-profiles -> resource default/Deployment/test failed:
1. autogen-app-armor: Validation error: Specifying other AppArmor profiles is disallowed.
