ci: bootc end-to-end support

[martinpitt]

These were applied in linux-system-roles/sudo#59 and lay the groundwork for adding bootc end-to-end tests. The changes are backwards compatible and no-ops for roles without e2e tests. Preferably they can get mass-deployed, to avoid having to cherry-pick all these changes manually.

Summary by Sourcery

Enable bootc end-to-end tests by extending the QEMU CI workflow with Podman 5.x support, customizable tox arguments, and a new validation step for bootc images, and bump tox-lsr to version 3.10.0.

CI:

• Upgrade Podman to 5.x via apt pinning for bootc scenarios
• Pass custom TOX_ARGS and add skip-tags for bootc-e2e in the tox invocation
• Add a QEMU-based bootc validation tests step that runs tests against generated QCOW2 images and logs results

Reviewer's Guide

This PR enhances the CI workflows to support bootc end-to-end tests by conditionally upgrading podman, extending the tox invocation to accept bootc-specific arguments, adding a new QEMU-based bootc validation step, and bumping the tox-lsr version to 3.10.0.
