Dockerfile: install git to populate node version string

Without the git CLI, `go build` will not produce the embedded VCS metadata that's used to report the commit hash in node version string. This fixes the `1.72.1-ERR-BuildInfo` version string reported to Tailscale. Fixes #140 Signed-off-by: Andrew Lytvynov <[email protected]>
