PATCH: completion option updates for recent BSD releases

[Oliver Kiddle <opk@zsh.org>]

This patch covers changes in the recent OpenBSD 6.9 and DragonFly 6.0.
I also checked NetBSD 9.2 but there were no relevant changes in that.
Though I did notice completion for head was missing a couple of options
for NetBSD (that were newly added in DragonFly).
