Retire SR-IOV, NIC tuning and watchdog scripts to unused/
Checked against the live host. None of these are in service: - sriov-enp4s0.service and set-ixgbe-vfmacs-enp4s0.sh target enp4s0f1np1, which no longer exists; sriov_numvfs is 0 on every port and the unit was never installed. - nic-performance-tweaks.service was never installed either, though its interfaces do still exist, so it would work if reinstated. - vm-watchdog.sh watches VMID 2801 "pfsense", which no longer exists. - lxc-watchdog.sh still carries the upstream example targets: CT 100 and CT 101 on 192.168.31.0/24, a subnet that is not in use. Neither watchdog is scheduled; there is no root crontab. The watchdog config moves to unused/conf/ alongside them, so the scripts resolve it unchanged from their new location.
