    ovirt-disk: Fix content type property name
    
    Instead of using underscore, which is not accepted, make use of a dash,
    avoiding error messages like the following:
    
    GLib-CRITICAL **: g_param_spec_internal: assertion '!(flags & G_PARAM_STATIC_NAME) || is_canonical 
(name)' failed
