Make the desktop files of the KCMs use icons in icon naming

specification style. KInfoCenter KCMs left out for now,
but I think I got hold of all other KCMs in workspace.

If you want to see some of those icons (in System Settings or
for single KCMs), do a kbuildsycoca4. In order to function
correctly, we still need fallbacks implemented.
