[PATCH manager] postinst: add nbd devices to global lvm filter.

[Daniel Herzig <d.herzig@proxmox.com>]

This patch adds nbd-devices to the global filter list of LVM for new
installation.

This is to avoid clashes with existing VGs/LVs on the host system, if
external disks mapped via the nbd kernel driver contain the same
naming scheme (eg. nested Proxmox VE systems with LVM/ext4
installation on an LVM/ext4 host).
