Fail-safe OpenVINO build; fix edgetpu path

Browse Source 
Use an absolute path for the downloaded edgetpu model to ensure it lands at /edgetpu_model.tflite. Wrap the OpenVINO build step in a conditional: only copy the generated .xml/.bin and fetch the COCO class file if build_ov_model.py exits successfully; otherwise emit a warning and allow Frigate to fall back to the CPU model (handles machines without required CPU instructions).
