chore(3p/sources): bump to OpenSSH vulnerability hotfix

See https://github.com/NixOS/nixpkgs/pull/323753 for details.

Changes:

* git: temporarily comment out dottime patch (it doesn't apply, but it's not critical)
* third-party/cgit: use an older git version where dottime patch still applies
* 3p/crate2nix: remove crate2nix patches included in latest release
* tvix: remove unneeded defaultCrateOverrides (upstreamed to nixpkgs)
* tvix: regenerate Cargo.nix
* tvix/nix-compat: remove unnused AtermWriteable::aterm_bytes pub(crate) function
* tvix/nix-compat: remove redundant trait bounds
* tvix/glue: use clone_into() to set drv.{builder,system}
* tools/crate2nix: apply workaround for https://github.com/numtide/treefmt/issues/327
* toold/depotfmt: expose treefmt config as passthru
* tools/crate2nix: undo some more hacks in the crate2nix-check drv
