distro/fedora: redo package set for qcow2

Our package set was quite outdated. Let's sync it with the Fedora Cloud
kickstart:
https://pagure.io/fedora-kickstarts/blob/c3b160775a3b159f949ba931dcb68e520a460e12/f/fedora-cloud-base.ks

I manually compared built images and our image contain kernel, kernel-modules
and linux-firmware above the official package set:

- removing kernel and kernel-modules is tricky, because we always assume that
  the default kernel is called kernel.
- removing linux-firmware is a big hack, since it breaks the RPM dependencies
  inside the image.

Thus, let's ignore these for now, it's definitely better than before.
