chore(3p/sources): Bump channels & overlays r/3942

Use nixos-unstable-small which fixes CVE-2018-25032
(out of bounds write while compressing).

* //users/grfn/xanthous:

  - Supporting random-fu 0.3 requires considerable changes and patching
    random-extras (https://github.com/aristidb/random-extras/pull/5).

    For now we downgrade random-fu and its dependency rvar to 0.2.*,
    forcing us to build xanthous with GHC 8.10.7, due to random-fu 0.2.*
    not supporting that version.

    Nix expressions for the downgraded packages are checked in to avoid
    the potential need to compile Haskell at pipeline eval time.

  - generic-arbitrary exposes a GenericArbitrary newtype now.
    This means we no longer have to implement it in xanthous
    downstream and patch generic-arbitrary to expose the
    GArbitrary type class.

  - Minor adjustments for lens 5.0:

    Xanthous.Game.Memo: clear needs to use ASetter' instead of Lens'

    Xanthous.Data.EntityMap: TraversableWithIndex no longer has an
    itraversed function.

  - Xanthous.Orphans: adjust for aeson's KeyMap, use KM.size explicitly
    instead of relying on MonoTraversable's length

* //nix/buildLisp: the CCL issue has resurfaced, disabling the
  implementation once again.

* //3p/arion: remove, as depot uses the nixpkgs package of it anyways.

* //users/wpcarro: accomodate GHC 9.0.1's stricter parsing of operators.

* //users/tazjin: disable rustfmt as it stopped respecting settings

* //3p/overlays: upgrade home-manager until fix for serivce generation
  has landed upstream

* //users/grfn/system: remove rr override, as the pinned commit is part
  of the 5.5.0 release shipped by nixpkgs.
