Use the correct io.Writer for k0sctl kubeconfig output (#413)

s0j · web-flow · commit 8eda2843f271 · 2022-09-05T15:44:48.000+03:00
Redirect the output of `k0sctl kubeconfig` to the `io.Writer` being
used in `cli.App` instead of `fmt.Println()`. This fixes the usage
of `k0sctl` as a module when configured with an `cli.App.Writer`
other than `os.Stdout`
