[SPARK-22341][yarn] Impersonate correct user when preparing resources.
The bug was introduced in SPARK-22290, which changed how the app's user
is impersonated in the AM. The changed missed an initialization function
that needs to be run as the app owner (who has the right credentials to
read from HDFS).
