update: add --force argument.
Add a `brew update --force` to side-step all of the clever optimisations
we have to detect if an update is unnecessary. That means if those
optimisations go wrong in future we can tell people just to run this
single command.
This would have been a useful workaround for the issue fixed in 985c672.
