Use full path for executing pam-auth-update

On Debian-based distros, pam-auth-update is located at /usr/sbin/pam-auth-update. However, when running chef-client as a cron job, /usr/sbin may not be available on the path, resulting in an error. This affects nodes using the Azure Chef extension, among others.
