Add a new GitHub Actions workflow that spins up raw QEMU VMs to run the integration test suite, so tests can run without relying on GitHub-hosted infrastructure (useful for external contributor PRs that lack access to internal runners). - Introduce ci/qemu-vm.sh to boot and manage QEMU VMs, sharing the workspace via virtiofs. - Add cloud-init configs for CentOS/Fedora and an Ignition config for RHCOS to provision the VMs. - Extend the test matrix to CentOS 9/10, Fedora 44, and multiple RHCOS releases (4.16-4.22) across RHEL 9/10. - Update tests/conftest.py and tests/containers.py for the new VM provisioning workflow.

Preserve interactive SSH mode when no command is supplied.
When cmd_ssh receives no arguments, printf '%q ' "$@" produces a quoted empty command. vm_ssh passes that value to ssh, so SSH runs a remote command instead of opening the documented interactive session.
If no command is supplied, invoke SSH without a remote command. For a non-root user, request a TTY and run sudo -n -i.
