Create `log.dirs` directories in `_setup` recipe

Noticed today that the directories specified in the `log.dirs` attribute actually wasn't created in any recipe, though they probably should?

@dpkp, do you have any input on this, as I understand that you actually got a cluster setup using this cookbook? IIRC Kafka creates the directories if they don't exist, but I'm not sure if they get the right owner, group and permissions?
