    util-app: Don't add OS to download list if URL is null
    
    In issue #726 we see a case for when an OSes added to our
    recommended-downloads.xml list doesn't have an URL, causing an error.
    
    Since we encourage downstreams to tweak this list, we should prevent
    such synchronization (osinfo-db and Boxes) issues from happening.
    
    Let's check for media.url before adding the OSes.
