Use linux watchdog to restart the Pi when the remote app crashes

/dev/watchdog

Instead, maybe just relaunch the app. Create a simple script that periodically checks if the app is running.

This issue should be transferred to remote-os.

Relaunch can be defined in the systemd app.service definition:

...
[Service]
ExecStart=/usr/bin/yio-remote/app-launch.sh
Restart=on-failure
Type=forking
PIDFile=/var/run/remote.pid
...

app-launch.sh probably needs a little rework since the remote process is also forked there.
A system watchdog would still be a good idea for hard crashes.
