Commit: https://git.seco.com/seco-ne/yocto/layers/meta-guf-distro/-/commit/a6a685456a562726f915213e8d69b535c5d4aaab

network: Fix distrooverride for network: set mac address, removed networkd

The distrooverride changed from guf to seconorth, but these recipes haven't been adapted yet and the syntax was not changed to the new.
