qemu: add meta.mainProgram

[PedroRegisPOAR]

Motivation for this change

Using the nix cli with flakes it should be possible to not get a error message when the following command is ran:

nix run nixpkgs#qemu -- --version

Produces this error:

error: unable to execute '/nix/store/vfyx7mmb2q3csw1qphdcmfpx85d59jpm-qemu-6.1.0/bin/qemu': No such file or directory

Expected something like:

QEMU emulator version 6.1.0

Things done

Just added mainProgram = "qemu-kvm"; to meta and it works 🎉 🚀

Tested with:

nix run github:PedroRegisPOAR/nixpkgs/nixpkgs-unstable#qemu -- --version

Not sure I corrected the message right. I used GitKraken (UI) way to use git, so it allowed me to change the commit and pull before push, so it has a "merge commit" too 🤔

Yeah, definitively looks wrong. You should have only your commit here.

Also, there is 3 commits. Your old commit with the old commit message is still here.
