Summary:
This adds a new test suite, run for Workstation and KDE live
images, which does not create a user during install. It then
expects initial-setup (KDE) or gnome-initial-setup (Workstation)
to appear after install, creates a user, and proceeds with
normal boot.
Note the ARM image test already covers the initial-setup text
mode, and the ARM minimal image is the only case where that
actually matters (it's not included in Server).
Test Plan:
Run the new tests, check they work. Run all old
tests, check the changes didn't break them.
