Add `fuse`, `ceph` and `rbd-nbd` to the `linuxkit/alpine`

ceph and rbd-nbd are currently only in edge testing, which makes it harder.

Would be good to have them available in the base since we already enabled CEPH support in the kernel recently.

yeah I agree, that would be great!

Try to run restic tests, when build RPM with mock. Seems fuse still absent in linuxkit
