[gtk+] cups: Fix gettext usage

[Bastien Nocera <hadess src gnome org>]

commit 97d27ca2f8a22ee3a1043fa1ad0e0813d8293f13

    cups: Fix gettext usage
    
    The previous patches didn't mark some strings as to be translated, and
    tried to translate strings with a variable part already inside the
    string, which isn't going to work.
    
    Mark the strings as translatable with context, and also make sure to
    translate static strings when getting them out of their structure.
