clarify that ~/.cfncluster should be a directory

During first setup I skipped the suggestion to run the command with no
config yet since I knew it would fail.

Instead I first cp'd the config file, but that produces a **file** named
`~/.cfncluster` instead of the desired file in a directory named
`~/.cfncluster/config`.
