bugfix in util.sh, fix silent hang

`gcloud preview --help >/dev/null 2>&1` would silently hang if the preview component was not installed. Instead, let stderr flow normally. to reproduce the bug and verify the fix: 1. gcloud components remove preview #answer yes 2. gcloud preview --help >/dev/null 2>&1 #note the hang, ^C 3A. gcloud preview --help >/dev/null #now prompts you to install preview component the fix also works when run via "kube-up.sh" alternatively: `gcloud -q preview --help >/dev/null 2>&1` will silently install the missing preview component
