[IMP] script todo: « Tester une VM » — option d'installer un autre navigateur

Le choix du navigateur propose désormais « [i] Installer un autre
navigateur » en plus des navigateurs déjà installés. L'option ouvre le
sous-menu d'installation (choix w3m/lynx/links/elinks, commande adaptée à
l'OS, validation), même s'il existe déjà un navigateur.

Le flux d'installation est extrait dans _qemu_install_cli_browser
(réutilisé quand aucun navigateur n'est présent ET via l'option [i]).
