Hue package init script for RedHat/CentOS does not set proper lock file under /var/lock/subsys on condrestart stage

There is a syntax issue present in /etc/init.d/hue residing in the hue-common package:

condrestart) 
 [ -f /var/lock/subsys/<service> ] && restart || : 
;; 

Instead of using <service> should be replaced with the actual service, hue.

The fix is fairly simple, attaching the patch.
