PATCH: update completions for openbsd 6.3

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

The new OpenBSD release has a few command option additions affecting
completions.

cu is not especially OpenBSD specific but _cu was written for it so I
added the new option along with a few common net/freebsd options but
more could be done to flesh it out for different systems. I tend to use
screen if I need a serial connection.

Otherwise, dhclient, script and uniq gained options. grep did too (-m)
but that's already completed.

Oliver
