In the case of config files, we want a local sysadm dir added as well.

The priorities is as follows:

 - peoples homedir (.kde4)
 - for config files, /etc/kde4/
 - what's defined in KDEDIRS
 - the default install path.

With this patch, we can also install all config files into /usr/ as they just can get
overridden by adding new files to /etc/kde4 by the sysadm.
