[libgovirt] Fix OvirtApi parsing

[Christophe Fergeau <teuf src gnome org>]

commit 27d16b1dedc1fb5abefc0466d18e2f843bc28173

    Fix OvirtApi parsing
    
    This is the only resource-like object which does not have href/guid
    attributes, so this commit (clumsily) special case this class in
    the OvirtResource parsing code.
       (use "git reset HEAD <file>..." to unstage)
