curl: apply eventfd free patch

[szlend]

Fixes #373540

Next scheduled release for curl is Feb 5th + the time for staging to build. I think it's better to patch this now.

Applying on 24.11 as well in #373688

We absolutely cannot eat a curl rebuild this far into the staging cycle.

Given the other PR, I don't think it was even intended.

Fair if it's that far in the build process. When is the next staging merge scheduled?

I think the curl 8.11.1 upgrade is going to cause a lot of headaches given our experience in CI after the channel update in nixos-24.11. Arch Linux maintainers ran into the same issue with pacman after updating curl.

Right now, merging staging-next to master only waits for humans fixing regression(s).

I would argue we want to backport this to 24.11 asap, hence why I manually targeted staging-next-24.11 in the other MR. But I can close it if there's disagreement.

Changed base to staging and rebased.

Edit: Ah staging-next-24.11 is currently empty, so we can just automatically backport. All good then.
