Enabling services with chkconfig fixed. Canonified classes where matched...

... against uncanonified classes.

In the chkconfig part of standard_services uncanonified classes (using the service name) are created if a service is not enabled with chkconfig. Those classes are matched against canonified classes. As a result, it never matches and services will not be enabled at boot time. This commit should fix the error. 
This should also use ``$(c_service)``, shouldn't it?
