Subject: [PATCH] pkgs/stdenv/linux: update riscv64 bootstrap-files

This PR updates the bootstrap tarballs for riscv64-linux with new Hydra-generated ones.

Fixes #275848 (bootstrap assembler too old to build gcc 13).

I'll be following the script used in #151399, #168199, #183487, and #188334.

Files came from [this](https://hydra.nixos.org/build/246376732#tabs-summary) Hydra build, which used nixpkgs revision 160cedc144aced7a35a91440b46b74ffacd52682 to instantiate:

```
/nix/store/cpiajh4l83b08pynwiwkpxj53d78pcxr-stdenv-bootstrap-tools-riscv64-unknown-linux-gnu.drv
```

and then built:

```
/nix/store/8a92pj40awdw585mcb9dvm4nyb03k3q3-stdenv-bootstrap-tools-riscv64-unknown-linux-gnu
```

I downloaded these files from Hydra and prefetched them into the nix store with the following commands:

```
STOREPATH=8a92pj40awdw585mcb9dvm4nyb03k3q3-stdenv-bootstrap-tools-riscv64-unknown-linux-gnu
OPTIONS="--option binary-caches https://cache.nixos.org --option trusted-public-keys cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY="
nix store prefetch-file \
  file://$(nix store add-file --name bootstrap-tools.tar.xz  $(nix-store ${OPTIONS} -r /nix/store/${STOREPATH})/on-server/bootstrap-tools.tar.xz)
nix store prefetch-file --executable \
  file://$(nix store add-path --name busybox $(nix-store ${OPTIONS} -r /nix/store/${STOREPATH})/on-server/busybox)
```

These commands produced the following output:

```
Downloaded 'file:///nix/store/xs74wcxq3qc12plfc70fds8inbndhcfm-bootstrap-tools.tar.xz' to '/nix/store/3fal4gikp92013kac6rdmfbrch2s859b-xs74wcxq3qc12plfc70fds8inbndhcfm-bootstrap-tools.tar.xz' (hash 'sha256-0LxRd7fdafQezNJ+N2tuOfm0KEwgfRSts5fhP0e0r0s=').
Downloaded 'file:///nix/store/9ndpna6jrlac4y9fappdjm0sxx0g2bja-busybox' to '/nix/store/kb7wyy30y1gxcmdajljr26kxxac606qa-9ndpna6jrlac4y9fappdjm0sxx0g2bja-busybox' (hash 'sha256-OGO96QUzs2n5pGipn/V87AxzUY9OWKZl417nE8HdZIE=').
```

I used the hashes from the output above to create the `fetchurl` invocation which is part of this commit.

I then started the bootstrap with the following command:

```
nix build -L -f . --arg localSystem '(import ./lib).systems.examples.riscv64' hello
```

As @lovesegfault requested, here are the the `sha256sum`s of all the `on-server` components for extra verification:

```
sha256sum /nix/store/${STOREPATH}/on-server/*
```

which produced the following output:

```

```
