PATCH: shutdown completion

PATCH: shutdown completion

[Oliver Kiddle]

There's a shutdown completion in the zsh-completions project but it is
system specific. This one handles the major BSDs and Solaris. On Linux,
shutdown tends to come from the init system. systemd is handled
otherwise you only get the most common BSD-style options.

Add support for macOS.

Are there any linux systems (not using systemd) where
'-p' (lower case 'p') means 'turn off power after shutdown'?

None of the linux systems I've looked at have -p. -P does occur.
More significantly, the patch uses args= where args+= was needed and
loses a bunch of options.
