When keystore was replaced with keystore2 in Android 12, the SELinux
class of keystore keys was changed from keystore_key to keystore2_key.
However, the rules that granted access to keystore_key were never
removed. This CL removes them, as they are no longer needed.
Don't actually remove the class and its permissions from
private/security_classes and private/access_vectors. That would break
the build because they're referenced by rules in prebuilts/.

Wi-Fi vendor AIDL service uses NDK to register itself to service
manager. AServiceManager_registerLazyService registers an
IClientCallback to service manager. The callback is invoked when there
is a transition between having >= 1 clients and having 0 clients (or
vice versa). Please check IClientCallback.aidl. As a result servicemanager may
make binder call to Wi-Fi vendor AIDL service. Since this is not allowed
per current SE policies, "avc denied" occurred:
