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

* //3p/sources: temporarily switch to nixos-unstable-small, since it
  includes:

  - evans update we are interested in, allowing us to drop our evans
    patches.
  - awscli2 update that unbreaks //users/grfn

* //3p/overlays/tvl:

  - drop evans patches
  - update tdlib to 1.8.11 to make tazjin's emacs happy
  - drop obsolete mullvad workaround

* //users/grfn/keyboard: disable -Werror for array-bounds warnings.
  Seems like a non-trivial job to resolve the warning properly,
  hopefully GCC 12 still generates the same working code as GCC 11 used
  to.

* //users/grfn/system/home: remove yubikey-manager-qt.
  Yubico can't seem to keep that on pace with yubikey-manager. It
  requires a <5 version of the latter which is incompatible with the
  recently released cryptography >= 39.

* //3p/gerrit: update changed FOD hash for the fetch step
