Fix sed command to not try shell redirection RunCmd uses Go's os/exec library to run commands directly. Since these are not run through a shell, we can't use shell syntax for piping or file redirection. The proper way to do that is to create a Command object and set the Std{in,out,err} pipes appropriately. Luckily sed can handle the behavior we need without having to manually set this up. fixes https://github.com/kubernetes/kubeadm/issues/472
