[PATCH container] Fix bug #6040 in the exclusion pattern of tar

[Orwa Diraneyya]

From: Orwa Diraneyya <diraneyyaorwa at gmail.com>

After this fix, users of Proxmox will be able to
use the root filesystem tarballs found publicly
(e.g. at https://cloud-images.ubuntu.com/) as LXC
container templates.

Currently, this results in a container-creation
failure due to the root folder `/dev` exclusion
pattern being ineffective.

The bugfix is also announced on the dev mailing
list (mailman.74.1735960093.441.pve-devel)
