refactor(ci-builds): Split up CI builds into multiple buckets r/1076
These categories separate CI targets, which hopefully avoids the
out-of-space errors we have been seeing on Sourcehut.

The sets of CI build targets are made available in the depot itself so
that besadii can be updated to create a new build for each target
group.

For convenience, 'ciBuilds' contains an '__allTargets' attribute which
combines the contents of each target batch - this makes it possible to
still invoke a build for everything by using:

  nix-build -A ciBuilds.__allTargets

Note: Some targets that were previously built in CI aren't anymore,
most importantly my NixOS systems which don't fit on Sourcehut.
