    depmod: Fix modules.dep truncation
    
    If a wrong module name (or a nonexistent module) is passed to depmod it
    will truncate the modules.dep file and segfault.
    
    The problem is that even if the modules list is empty, depmod will try
    to do its job. This is wrong, it should do nothing if no modules have
    been found.
