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().
