libedgetpu1 missing in arm64 2.9.7 build

Fixed by running the install steps in the container:
``` 
echo "deb https://packages.cloud.google.com/apt coral-edgetpu-stable main" | sudo tee /etc/apt/sources.list.d/coral-edgetpu.list
curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
apt-get update
apt-get install libedgetpu1-std
```
and restarting the respective module. Should be an easy fix in the dockerfile.
