Handle android.media.ResourceBusyException in MediaDrm::openSession().
Based on Android MediaDrm API documentation:
https://developer.android.com/reference/android/media/MediaDrm.html#openSession()
openSession() could actually throw ResourceBusyException. This is added in API
level 19. To be compatible with both API level 18 and 19, we cannot catch
ResourceBusyException directly. Instead, we catch NotProvisionedException
explicitly, and catch all other MediaDrmExceptions together.
