Check same uid for permission and app-op

In permission checker we used to check the permission for the passed in
uid but the opp-op for the Binder.getCallingUid. In the case the calling
identity was cleared, PermissionChecker ended up checking the app-op of the
current process (often the system server).

Now we check the uid for both the permission and the app-op.

Test: Called PermissionChecker.checkPermission with the calling indentity
cleared.
