Optimize upstream skopeo container image build

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.
