Code review comment for ~xnox/britney/+git/britney2-ubuntu:ignore-di

Right, this should be configurable please, so that (1) it can be done differently for stable releases, (2) it can be upstreamed - which should ideally be done ASAP if & when we merge something here.

See britney1 make_b2_config for the config file generation. However, for testing, you can ignore b1 and use a static configuration.

Question: would it be better to stop building udebs at all (noudeb profile, I'm thinking like we do for nocheck on riscv64)?
