chore(3p/sources): Bump channels & overlays r/5211

* //users/grfn/system/home/modules:

  The MultiMC saga continues with:

  > PolyMC has been removed from nixpkgs due to a hostile takeover
  > by a rogue maintainer. The rest of the maintainers have made a
  > fork which is packaged as 'prismlauncher'.

* //third_party/overlays:

  Override tdlib to 1.8.7 while waiting for nixpkgs to catch up.

* //users/tazjin/finito:

  Disable on CI temporarily as it has been broken by some change
  in nixpkgs, now failing to compile a dependency.
