[glib/wip/hadess/update-docker-packages: 1/4] ci: Add podman support

[Bastien Nocera <hadess src gnome org>]

commit 265fc7e0209293884bed13a5caf9c82dfdc9b394

    ci: Add podman support
    
    If podman is used, as is usually the case on a Fedora Workstation
    installation, make sure not to use "sudo" as that's not needed, but ask
    podman's backend (buildah) to create Docker compatible images.
    
    See https://gitlab.gnome.org/GNOME/glib/merge_requests/1255
