Fix bug where installing crowbar hangs.  This was due to pull

https://github.com/crowbar/crowbar/pull/1909

which needed to be manually merged to roxy.
Fixed bug in install-chef.sh in both pebbles and roxy where the
/var/run/crowbar dir must exist before chef_or_die is called to
prevent installation hang.
