Fix crypton-x509-system win cross-compile

[rafaelrc7]

Hello, I'm not sure what the contribution rules are, so if there is something wrong with this PR, just tell!

I recently added haskell.nix to a small personal project of mine, so that I could cross-compile it to windows for a friend. However, a dependency crypton-x509-system-x86_64-w64-mingw32-1.8.0 is broken, erroring with:

Basically, this package was recently updated and its cabal file changed, making the hakell.nix patch fail. I updated the patch and using it, my project builds fine. I can confirm this change is the only thing needed to fix it by changing my flake input to haskellNix.url = "github:rafaelrc7/haskell.nix/fix/crypton-x509-system-win";.
