fedora: remove iot-qcow2-image function

The function was added accidentally [1] while rebasing a PR from
osbuild-composer [2].  During the rebase, the functionality of
iotQcow2Image() was merged with the existing iotImage() function since
they share most of their code but the function wasn't removed.
