PATCH: update util-linux completions

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

This updates completions for some of the util-linux tools to 2.30.1.
losetup seems to have been changed around a lot yet again.
Completion for wipefs is new.

For some things that come with util-linux, there are other
implementations around, last for instance. It would be good to handle
such cases better.
