WIP: Refresh Podman user namespace mappings on Rawhide #1689

Some CI jobs on Fedora Rawhide failed with rootless Podman builds due to stale or missing UID/GID mappings, even after installing shadow-utils-subid-devel:

Error: cannot find mappings for user zuul-worker in /etc/subuid

Force a refresh of Podman’s user namespace mappings with podman system migrate, which re-reads /etc/subuid and /etc/subgid and applies default ranges when available.

Once the Rawhide base image includes proper mappings by default, this workaround can be removed.

Thanks for looking into this, @calancha ! Is this pull request still needed? #1688 looks more complete.
