fix(openwrt-vm): leave the NIC untagged on a bridge without a port (#18473)

Browse Source 
Advanced mode prefills the LAN VLAN with 999. On a bridge with no
physical port that is not VLAN-aware (an internal vmbr1, the usual LAN
choice) pve-bridge cannot tag the tap, and qm start failed with "no
physical interface on bridge 'vmbr1'". The tag is dropped there with a
warning, for LAN and WAN alike.

The scripts base still pointed at DevScripts, where this script was
removed on 10-09, so every run was reported as a DevScripts run.
