Remove Podman-Docker compatibility layer when installing

[mattroot]

This might be problematic on RHEL-based systems due to Podman being pushed by Red Hat.
From what I know, it only affects Fedora, Alma and Rocky.

Also, a quick trailing space fix.

BTW: T-Pot does not run on this compatibility layer, at least it didn't back on 22.04.

Thanks for the PR. Given podman-docker is having podman as a dependency it would make sense to include podman as well:

package: podman-docker-5:5.0.0-1.fc40.noarch
  dependency: /usr/bin/sh
   provider: bash-5.2.26-3.fc40.aarch64
  dependency: podman = 5:5.0.0-1.fc40
   provider: podman-5:5.0.0-1.fc40.aarch64

package: podman-docker-5:5.1.1-1.fc40.noarch
  dependency: /usr/bin/sh
   provider: bash-5.2.26-3.fc40.aarch64
  dependency: podman = 5:5.1.1-1.fc40
   provider: podman-5:5.1.1-1.fc40.aarch64

Podman itself does not get in the way, it's just the compatibility layer. Although we can remove it, if we intend to hold just T-Pot on a said machine (which makes sense)
