Uv4l trial on Buster

As of 2019-10-15 there is no official Buster support for uv4l yet see e.g. https://www.raspberrypi.org/forums/viewtopic.php?t=247305

We will try using the commands for Raspberry Stretch

curl http://www.linux-projects.org/listing/uv4l_repo/lpkey.asc | sudo apt-key add -
echo "deb http://www.linux-projects.org/listing/uv4l_repo/raspbian/stretch stretch main" >>  /etc/apt/sources.list
sudo apt-get update
sudo apt-get install uv4l
sudo rpi-update
sudo apt-get install uv4l-server uv4l-uvc uv4l-xscreen uv4l-mjpegstream uv4l-dummy uv4l-raspidisp
sudo apt-get install uv4l-webrtc
