Listen and broadcast on all interfaces by default

[yegorich]

socketcand tries to use eth0 by default. In the modern systems there is no such network interface as the new approach names the interfaces according to their bus location. Hence socketcand fails to send beacons.

Not a fix, but this bash script starts a socketcand instance on every active interface it can find without disabling beacons
