First Groovy Gorilla test rebuild

[Matthias Klose]

The first test rebuild of Groovy Gorilla was started on July 27 2020 for all
architectures (except riscv64), all components. The rebuild is finished for the
main component (except for armhf/arm64, still working on some heavy daily PPA
test builds). It is still running for the universe/multiverse components.

Results (please also look at the superseded builds) can be found at

https://people.canonical.com/~doko/ftbfs-report/test-rebuild-20200728-groovy-groovy.html

Additional build failures for packages in groovy-proposed (not yet in groovy)
can be found at http://qa.ubuntuwire.com/ftbfs/

Please help fixing the build failures.
