Add vfkit to brew

[cfergeau]

More projects than just crc are using vfkit (podman, #38, ...). Having vfkit available in brew would make it a lot easier to install.
I made a formula as part of crc-org/crc#3476 , it's still available at https://github.com/cfergeau/homebrew-crc

This needs to be submitted upstream.

At the moment, vfkit can be installed with:

brew tap cfergeau/crc
brew install vfkit

At the moment, vfkit can be installed with:

brew tap cfergeau/crc
brew install vfkit

But it provides only 0.5.1. This breaks with my script:

Error: unknown option for usb-mass-storage devices: readonly

Can you add 0.6.0 to your brew tap?

Can you add 0.6.0 to your brew tap?

There was an open PR for this, it's now merged.

At the moment, vfkit can be installed with:

brew tap cfergeau/crc
brew install vfkit

This builds vfkit on the machine, which is very slow. For example in CI I need to rebuild vfkit for every run.

Can we change to install a built executable?

For now I'm installing vkfit from the github releases instead. Maybe this should be documented instead or in addition to brew?
