systemctl: allow multiple arguments to --type
This mirrors --property, and is generally useful. New functionality is used in bash completion. In case of zsh completion, new functionality is less useful because of caching. Nevertheless, zsh completion for restart is made to behave more-or-less the same as bash completion. At least sockets can be restarted.
