Enable edgetpu_demo in Excelsior

Currently only --device mode is tested. Streaming mode is diabled.
Also disable looping since there's issue decoding the end of the video.
Change the display mode to window to reduce the latency. Playback
resolution is set at 720p.

Test: edgetpu_demo --device @ Excelsior
