fix: build of kubelet with Ceph on arm64

Old release 'octopus' is EoL:
https://docs.ceph.com/en/quincy/releases/index.html

New releases pacific/quincy have a problem with arm64 packages: they are
not built for arm64, which breaks the install. Use `ceph-common` from
Debian for `ceph-common` on arm64 as a workaround for now.
