#774415: devscripts: please add the srebuild wrapper for reproducible builds

I have to second the issues with srebuild. We invested a lot of time to utilize this tool in our rebuilds but faced consistent build failures.
The best explanation I could find was that the snapshots referred to in the .buildinfo files had expired. That's not conclusive (the output wasn't clear on the cause of failure) nor is expired repo metadata the fault of srebuild per se. But the issue was nonetheless a blocker.
PBuilder is the most consistent build tool we've seen thus far, will have to investigate debrebuild as well.

it uses snapshot.debian.org to find the snapshot with the right packages and then crafts either an sbuild command line that does the right thing or outputs manual apt-get command that will install what is necessary. Pbuilder support could be added but I do not understand enough pbuilder to know how to do that.
