With podman-remote we do not enter a our user namespace like we do with
local podman so we keep running with the real user id.
So if we then try to use chrootarchive as normal user it fails with:
creating mount namespace before pivot: operation not permitted
So simply revert back to the normal archive code.
Now the more interesting thing is we do have a test
"podman save to directory with oci format" but it never runs
rootless+remote in our CI system with our current matrix as we wanted to
reduce jobs.
So rethink the matrix and add one such job as this shows it is needed.
Fixes: 25aee24cbd ("use chrootarchive over plain archive package")
