Please add a test for CVE-2024-27297

It would be really nice, especially for downstream distributors, if

there was a test for CVE-2024-27297.

There is working code to test this in the excellent blog post on the

subject, which is a likely good starting point!

https://guix.gnu.org/en/blog/2024/fixed-output-derivation-sandbox-bypass-cve-2024-27297/

Super extra bonus points if the test is backwards compatible with guix

1.4 and 1.2 :)

live well,

FWIW, the reproducer from the blog is not working for me with guix 1.2:
