After enabling the calibre app, the app uses IP 127.0.0.1 to advertise
ODPS feeds via BonJour/mDNS. It breaks accessing freedombox.local as it now
points to 127.0.0.1.
This MR disables the BonJour in Calibre.
Fixes#2027.
Tests performed on both Debian stable and testing containers:
- Check the accessability of freedombox.local:
1) Before applying patch:
- Start the container, check on the host that freedombox.local points to
correct IP address of the container:
```
host$ avahi-resolve -4 --name freedombox.local
freedombox.local 10.42.1.166
```
- Enable the calibre app. Check on the host that freedombox.local
points to wrong ip address 127.0.0.1:
```
host$ avahi-resolve -4 --name freedombox.local
freedombox.local 127.0.0.1
```
2) Stop the calibre app, apply patch (update the calibre systemd service file,
reload systemd), restart the Service Discovery app, check on the host that
freedombox.local points to correct address.
3) Start the calibre app, check on the host that freedombox.local points to
correct address.
- All the calibre functional tests pass.
