Packit: update targets

[lsm5]

This commit removes f39 from the copr jobs and disables el9 podman revdep test jobs as we recently disabled f39 and el9 jobs on the podman-next copr due to golang 1.22 bump for our golang projects.

The copr and dist-git targets are also reused with yaml anchors wherever possible.

[packit-as-a-service]

We were not able to find or create Copr project packit/containers-container-selinux-330 specified in the config with the following error:

Packit received HTTP 500 Internal Server Error from Copr Service. Check the Copr status page: https://copr.fedorainfracloud.org/status/stats/, or ask for help in Fedora Build System matrix channel: https://matrix.to/#/#buildsys:fedoraproject.org.

---

Unless the HTTP status code above is >= 500, please check your configuration for:

1. typos in owner and project name (groups need to be prefixed with @)
2. whether the project name doesn't contain not allowed characters (only letters, digits, underscores, dashes and dots must be used)
3. whether the project itself exists (Packit creates projects only in its own namespace)
4. whether Packit is allowed to build in your Copr project
5. whether your Copr project/group is not private

Tests failed. @containers/packit-build please check.

@rhatdan @haircommander PTAL. Might wanna rebase #327 on this if it makes life easier.
