Since xanthous has a checked-in package.yaml and cabal file, the
haskellPackages build infrastructure will use the package.yaml file for
all builds. The resulting problem is that our CI won't actually catch build
failures that would be observable with cabal or when building from the
sdist.
We fix that by filtering out the package.yaml file in pkg.nix
additionally to the filters specified in .gitignore. For this we need
gitignoreFilter from gitignore.nix which we expose as part of a functor
set from third_party.gitignoreSource to maintain interface
compatibility.

Simplify the build infrastructure for creating shells etc. for xanthous,
including relying more heavily on stuff exposed in Depot anyway, using
shellFor in the shell.nix, and using the haskell.nix branch of all-hies
for a significantly simpler build. At some point the all-hies stuff will
likely want to be promoted up to //third_party, but for now it's
experimental enough that I don't want to bother other people with it.

CI doesn't have a nixpkgs channel (obvs), and we want to be able to
build from the depot tree, so reorder some stuff so we never depend on
nixpkgs
