Reduce Exoplayer load control buffer durations for Transformer demo app

Browse Source 
The default value is 50 seconds.
Changed it to 5 seconds.

This prevents the player from buffering too much data and causing the app to crash due to OOM.

This was reported in https://github.com/androidx/media/issues/1506
