bugfix in util.sh, fix silent hang

Browse Source 
`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
