Prevent copyNativeLib of package scanning to reduce booting time. 



Packagemanager do copyNativeBinariesForSupportedAbi for data apps(include updated system apps) every time.
And this takes a large percent of scanning time.
So, I added skip routine by check two confitions(isDexOptNeededInternal() and isUpdatedSystemApp()).
