Description of problem:
Building containers with buildah does not work because it chokes on missing container networking dependencies that exist with podman. That is, if you *just* install buildah and never install podman, buildah will not work because it cannot correctly set up networking.

This is because the package is missing the following dependencies that podman has:

Suggests: containernetworking-plugins >= 0.9.1-1
Requires: netavark
Requires: iptables
Requires: nftables


Version-Release number of selected component (if applicable):
1.25.1-1.fc37

How reproducible:
Always

Steps to Reproduce:
1. Install *only* buildah
2. Use "buildah bud" with containerfiles from https://pagure.io/nginx-vts-container

Actual results:
[root@097500dd2fd6 nginx-vts-container]# buildah bud -t nginx-vts-fedora -f Containerfile.fedora

Expected results:
Successful build of an image.

Additional info:
This also affects RHEL, since those packages are similarly configured.
