CI: Test bare RPM Install

Problem Description

A user is reporting that Rancher Desktop is failing to install on Fedora 44.

Proposed Solution

We should add to the smoke tests, to install Rancher Desktop from the repositories without having xvfb &c installed, to ensure that we can pull in the dependencies we need.

This obviously means we will not be testing running Rancher Desktop.

Alternatively, we can adjust our existing smoke tests so we install xvfb &c after Rancher Desktop has been installed.

Additional Information

error: Failed dependencies:
    glib is needed by rancher-desktop-1.24.0-2.1.x86_64
    gnutls-utils is needed by rancher-desktop-1.24.0-2.1.x86_64
    qemu is needed by rancher-desktop-1.24.0-2.1.x86_64

Also, qemu-img wasn't correctly installed afterwards:

exec: "qemu-img": executable file not found in $PATH
