nfs-mirror: exclude /vzdump/ — it was reaping the new VM-image backups nightly

Browse source 
nfs-mirror does `rsync -rlt --delete /srv/nfs/ -> /mnt/backup/`; any /mnt/backup
dir with no /srv/nfs counterpart is an orphan and gets --delete'd. vzdump-vms
(added yesterday) writes /mnt/backup/vzdump/, which wasn't excluded — so the
02:00 nfs-mirror run silently deleted both successful 40G devvm images
(verified: dir gone, 40G freed, despite status=0 success logs). Add
--exclude='/vzdump/' alongside the existing pvc-data/pfsense/pve-config/
sqlite-backup excludes that exist for exactly this reason. TDD-proven with an
isolated rsync --delete -n -v. backup-dr.md notes the dependency.
