git-cinnabar: disable version check

Not very useful when installed via Nix, and is generally undesirable
telemetry. This has the slight downside that new default features may
need to be audited upon version updates, current upstream master has
more upstream features but they are for determining the version via Git,
which also doesn’t apply to us.
