guix: nsis (Windows installer creator) is broken upstream #32674

This will become a issue when we want to bump the time-machine next, and it'd be nicer if this is fixed and shipped upstream, rather than us having to work around the issue:

See also: https://issues.guix.gnu.org/71548. Looks like this is still broken, but differently.

Does it depend on the build machine architecture?

It fails building on x86_64, aarch64 and with --system=riscv64-linux.

This will become a issue when we want to bump the time-machine next...

We definitely want to bump it to resolve #30206.

I've bisected the issue down to https://codeberg.org/guix/guix/commit/d6780d79d936832e1b2ea9103eefecd0a838fb16.

Fixed in https://codeberg.org/guix/guix/commit/514e7ac18a406cab6ad76efd615e2754d62ce238.
