fw: app: Reboot in case of no network
Because of an issue likely related to hardware design on the
nucleo_f767zi board (see issue [1] for details) the firmware should
reboot in case network access cannot be established after 4 seconds.
This makes the firmware more robust at the moment. As soon as
iot-contact hardware without this issue exists the behavior can be
changed again.
