Rudder

We added in #4900 a new directive to tell RPM that the policy_server.dat file is a "ghost" file, which means it is created by the package during postinst, but not actually installed:

%files
[...]
%ghost %{ruddervardir}/cfengine-community/policy_server.dat

However, RPM builds fail because this file does not exist:

02:11:26 Processing files: rudder-agent-3.0.0.beta2.git201412110149-1.EL.3
02:11:26 error: File not found: /var/tmp/rudder-agent-3.0.0.beta2.git201412110149-1.EL.3-root-root/var/rudder/cfengine-community/policy_server.dat
02:11:26 
02:11:26 
02:11:26 RPM build errors:

This seems braindead to me... But I can see an easy way round it, which is just to install a dummy file in it's place. This is what we already do for uuid.hive.
