bash-completion: systemd-nspawn update

Browse Source 
*Autocompletion for dirs, doesn't leave until you press space.
*Added tmpfs, volatile and network-macvlan options.

I tried with the SELinux options with seinfo(setools-console), but too
messy to get it right. Even Daniel Walsh haven't done it yet. :)
