[pkgs] Fixe

Si le répertoire .../sharing/private n'existe pas,
le déplacement des packages privés n'est pas possible.
La création du lien symbolique pose un souci.
Le lien s'appelle lui-même. Maintenant, on crée avec les bonnes permissions et les bons propriétaires dans le cas où le répertoire des partages privés n'a pas été créé à l'installation.
