update osx-kvm lock version

[ratson]

Update to the latest OSX-KVM

[MatthewCroughan]

Why? What are the differences we need?

[ratson]

@MatthewCroughan Not sure how this project affect from that, but the author has updated quite a few OpenCore files.
see kholia/OSX-KVM@a9b2014

[MatthewCroughan]

We should find a way to compile it ourselves, rather than relying on OSX-KVM

[Luflosi]

I think https://github.com/kraxel/imagefish is required for running the appropriate script from OSX-KVM, which is not yet packaged in Nixpkgs. I would be willing to help with packaging imagefish.

[MatthewCroughan]

Yeah, this is a more productive direction than just updating and depending upon OSX-KVM, I would love to move in that direction.

@MatthewCroughan I've just posted a wip PR for OpenCore to nixpkgs, if you get a chance, take a look. NixOS/nixpkgs#479419

OSX-KVM is basically a pre-built version of OpenCore which is bundled with a config file and also kernel modules which are injected into memory.

Building OpenCore from source gets a little bit closer to your goal, so I figured I'd tag you here.
