fw: app: update: Finish first HTTP PUT /update

This adds marking the application firmware image in the secondary slot
for a permanent update and rebooting the device.

It is a known bug that the corresponding HTTP request is never properly
closed since the device reboots while handling the request.

Nevertheless the current state works and enables remote updates.
