haskell-generic-builder: support badPlatforms

meta.badPlatforms allows us to exclude specific platforms from the list
of supported platforms without the need to explicitly substract it from
lib.platforms.all (or our inferior equivalent allKnownPlatforms) in
platforms. Thus it'll map nicely to unsupported-platforms in the
hackage2nix configuration in the future.
