Merge bitcoin/bitcoin#31323: guix: swap moreutils for just sponge

e8f50c5deb guix: swap moreutils for just sponge (fanquake)

Pull request description:

  Switch to building the only `moreutils` utility we actually need (`sponge`). This results in having less unused stuff in the Guix environment (i.e all the other `moreutils` utilities), and, the dependency graph is simplified. i.e we no-longer have a dependency on `perl`, `docbook` etc, for this package.

  Current `moreutils` dependency graph:
  ![moreutils](https://github.com/user-attachments/assets/b91a8609-1434-4094-ad12-93332737ef0f)

  In the Guix env, `chronic`, `combine`, `errno`, `ifdata`, `ifne`, `isutf8`, `lckdo`, `mispipe`, `parallel`, `pee`, `ts`, `vidir`, `vipe` & `zrun` (plus their `*.real` variants) are removed.
