components/9990-networking.sh: Add shellcheck override

To make `components/9990-networking.sh` shellcheck clean, add an override for specifying `HWADDR`, which is used by `do_iscsi` from `9990-mount-iscsi.sh`. Run shellcheck: ``` shellcheck -e SC1090 components/9990-networking.sh ``` Signed-off-by: Benjamin Drung <benjamin.drung@cloud.ionos.com>
