    wizard-source: Compose a human-readable media label
    
    To enumerate the medias of an operating system in a way that it
    isn't the literal file name neither a duplicated name, we should
    rely on the Osinfo.OsVariant "name" property.
    
    Unfortunately the Osinfo database doesn't contain proper names
    for OS variants. This way, these change introduce some heuristic
    to handle the most common iso file names for the operating systems
    available to download.
    
    If there will be a case not covered by this heuristics, we present
    the literal iso file name with %s/_/" "/g.
    
    This commit should be reverted when Osinfo contains distinguishable
    variant names.
