Avoid using sudo in makeVarRun()

[IgorMilavec]

Description

Some security products obstruct the usage of sudo, causing lima to fail with something similar to:
failed to run [sudo --user root --group wheel --non-interactive /bin/mkdir -m 775 -p /private/var/run/finch-lima]: stdout="", stderr="sudo: a password is required\n": exit status 1.
This command is run from makeVarRun() even if the directory already exists with appropriate permissions.
Could lima run sudo mkdir only if os.stat() call fails? This way the user could pre-create the path.

It could, but it would not really help, as it is just the first in a list of sudo commands Lima will execute to start the socket_vmnet daemon.

If you can't use sudo, then you will have to manage the daemon separately and not ask Lima to do it. See the https://github.com/lima-vm/socket_vmnet README about the ways to do this, e.g. to create a launchdaemon for the privileged socket_vmnet process.

If you can't use sudo, then you will have to manage the daemon separately and not ask Lima to do it.

Or use limactl create --vm-type vz --network vzNAT.
This doesn't need sudo at all.

Ah yes, I keep forgetting about that. However, it requires macOS 13.0.0 (Intel) or 13.3.0 (ARM) to use VZ.
