Part 2 of packaging bat with a bunch of missing dependencies.Here's what I've finished for now.Tested them all with ~guix build --rounds=4~ with only the x86_64 arch for now since I'm getting low disk space at the time.

Maybe I shouldn't include my comment inside of the patch. I only found out about --compose and --dry-run for git send-email JUST AFTER sending the patch series (why didn't I do that is beyond me). :-/

Apologies for the rookie mistake. For the reviewer, please remove those comments from the first patch if it's going to be applied. Thanks in advanced. :)
