os: Remove wizards setup (#588)

We do not build desktop images anymore.

Installing UI via
https://github.com/PlanktoScope/PlanktoScope/blob/master/documentation/docs/community/contribute/tips-and-tricks.md#graphical-ui
does not install/trigger piwiz wizard.

I'd also rater not overwrite the lightdm config or having to maintain
it.
