[3dprinter-general] Bug#1012575: Bug#1012575: libarcus: FTBFS with protobuf 3.20.1+

[Gregor Riepl]

Unfortunately, upstream hasn't fixed this issue yet:
https://github.com/Ultimaker/libArcus/issues/121

I suppose it would be best if we add your patch right away and drop it
when upstream releases a fix.

I took the liberty to branch from the last 4.13 release, so we can push
a fixed version before 5.0 arrives:
https://salsa.debian.org/3dprinting-team/libarcus/-/tree/testing

And I added it to the master branch for the 5.0 release as well.

@myon Please upload 4.13.0-3 when you have time. Thank you!
