Subject: [PATCH] wwan-config: Automatically restart service when it fails

It may happen that the service is failing, because the modem is in an
unpredictable state. To avoid this kind of cases and increase the
resilience of the system, systemd will now restart the service if it
fails, leading to a full power cycle of the modem.
