cirrus,ci: default to overlay for debian env 

In debian environment we are hitting an edge-case where older buildah
version is not compatible with newer podman version because both of them
are using different storage driver.

I.e
* Podmand defaults to native `overlay`.
* Older buildah version defaults to `vfs`.

See discussions below for more details
* containers#18510 (comment)
