COPR: Exclude ELN builds

The packit workflow for Podman and other repos has recently changed to
include the official rpm spec file upstream and have Fedora dist-git
sync from upstream on every release.
Ref: containers/podman#18465

This has made it necessary to verify ELN package build success in our
copr builds. And enabling ELN on copr is causing conmon-rs failures
Ref: https://copr.fedorainfracloud.org/coprs/rhcontainerbot/podman-next/build/6121423/

Since ELN is not an immediate concern, this commit will only do copr
builds for centos stream and fedora rawhide, 38 and 37.
