feat: add Amnezia check to Dockerfile healthcheck

This extends the Docker health check to check first if the WG interface is present and in a second step checks if the AWG interface is present.
If none are found the check fails.
The '2>/dev/null' silences errors for the case that the AWG kernel module is not installed.
