Update definition of occludingAppOnKeyguard

Don't consider an app occluding the keyguard
if the device is dozing (AOD or DOZE).

Flag: None
Test: atest OccludingAppDeviceEntryInteractorTest
Test: manually attempt UDFPS on AOD over an occluding
app (like maps in navigation), see regular AOD error message
