Running cross-platform compiles using emulation is a painfully slow process. Since CI-runtime is limited, improve image build time by leveraging the automatic RPM builds occurring for the podman-next COPR repo. This adds build-time efficiency by offloading the compilation task. Note: These RPMs are built any time the 'main' branch changes, so they'll still be very recent. https://copr.fedorainfracloud.org/coprs/rhcontainerbot/podman-next/ Signed-off-by: Chris Evich <cevich@redhat.com>
