Bug#963247: ignition-fuel-tools FTBFS with Protobuf 3.12.3

[jspricke at debian.org]

Hi,

seems like this was not enough:

/usr/bin/ld: /usr/lib/gcc/aarch64-linux-gnu/9/../../../aarch64-linux-gnu/libignition-fuel_tools4.so: undefined reference to `ignition::msgs::FuelMetadata::FuelMetadata()'

https://ci.debian.net/data/autopkgtest/testing/arm64/i/ignition-fuel-tools/6276839/log.gz

Looks like the new protobuf drops a symbol.
I'm not sure how to proceed:
- patch protobuf to get the symbol back?
- bump Sonames of all ign* packages?
- Any other idea?

Cheers Jochen
