Podman 5.0.2 on aarch64-darwin fails on podman machine start

[msgilligan]

Describe the bug

podman machine start fails on macOS (aarch64-darwin) when using the current unstable Nix pkgs podman (5.0.2)

Steps To Reproduce

Steps to reproduce the behavior:

1. nix profile install podman
2. podman machine init
3. podman machine start

Result of podman machine start is:

ERRO[0000] process 22471 has not ended                  
Error: exec: "vfkit": executable file not found in $PATH

Expected behavior

Starting machine "podman-machine-default"
API forwarding listening on: /var/folders/6d/12xt4b4m8xjf3t0059_w18bh0000gn/T/podman/podman-machine-default-api.sock
You can still connect Docker API clients by setting DOCKER_HOST using the
following command in your terminal session:

        export DOCKER_HOST='unix:///var/folders/6d/12xt4b4m8xjf3t0059_w18bh0000gn/T/podman/podman-machine-default-api.sock'

Machine "podman-machine-default" started successfully

Additional context

https://github.com/crc-org/vfkit seems to be missing.

If you install vfkit with Homebrew as follows:

brew tap cfergeau/crc
brew install vfkit

and then run podman machine start using Nixpgks Podman 5.0.2, the VM starts as expected.

A possible solution would be to:

1. Create a Nix package for vfkit
2. Configure the podman package so that it automatically installs vfkit on macOS
