[cwconfig] Retrieve real path of cubes directory
Since logilab-common 1.3.0, we have real path expansion
modutils.modpath_from_file. But the extrapath parameter that is passed from
cubicweb.schema reader may still have symlinks, so expand them here to
hopefully have consistent comparison in modpath_from_file.
