PATCH: update util-linux completions to 2.31

[Oliver Kiddle <okiddle@yahoo.co.uk>]

A few commands gained extra options in util-linux 2.31.

Linux's last has changed a bit. It was previously part of sysvinit-utils
and another GNU psacct implementation is also around. I think the
util-linux implementation is the only one we need to care about going
forward but let me know if not.

There's also a new completion for hexdump which was a BSD thing. It
looks like for util-linux, they've perhaps taken the BSD code and not
changed much besides adding long options.

Oliver
