Subject: fix(archsetup): write the cpupower config instead of editing a
 missing file

A VM test caught my cpupower step failing with sed exit 2: the cpupower package no longer ships /etc/default/cpupower, so there was nothing to edit. The step was non-fatal, so the install carried on, but the governor never got set.

I now write the file fresh with printf, which creates it whether or not one exists. The governor stays performance for the reasons in the surrounding comment.
