[bug#36132] [PATCH 1/2] installer: Partition as the last step.

[Tobias Geerinckx-Rice]

Multiple users have been understandably displeased after finding out
that their network card was unsupported, and Internet access mandatory,
after having already formatted their partitions.

* gnu/installer.scm (installer-steps): Run the ‘partition’ step just
before the ‘final’ one.
