Does this PR introduce a user-facing change?

update vfkit binary to v0.6.1 in macOS installer

I built the installer using make ARCH=aarch64 NO_CODESIGN=1 pkginstaller

then I was able to init/start a machine

LGTM, @Luap99 do we need to also get this into our images?

@benoitf this should make 5.5 which starts RC next week.

We have to many images. What images are you referring to, the macos CI workers? I that case they still install from brew until we switch to Adrian's worker poll logic hopefully very soon. Then we just use whatever is in our installer so we can actually have proper test coverage of such installer changes.
