mandos: Bug fix: Do multiprocessing cleanup correctly on exit

* mandos (main): Save module "multiprocessing" and open file "wnull"
                 as scope variables accessible by function cleanup(),
                 since the module and global variable may not be
                 accessible when the cleanup() function is run as
                 scheduled by atexit().
