Igor Pecovnik 4128ef0a83 apt: bypass apt-helper wait-online on multi-NIC systems
apt-daily-upgrade.service uses `apt-helper wait-online` as an ExecStartPre
step. On multi-NIC systems with systemd-networkd this helper directly calls
systemd-networkd-wait-online in strict mode, waiting for all managed links
to become online.

On boards with multiple Ethernet ports where some interfaces are commonly
unplugged, this results in repeated timeouts and causes
apt-daily-upgrade / unattended-upgrades to abort, even when at least one
interface is already fully routable.

Replace the ExecStartPre step with a direct invocation of
systemd-networkd-wait-online using `--any`, allowing the service to proceed
as soon as one interface is online.

This preserves the intent of waiting for network availability while making
the behavior robust on multi-NIC and router-style systems.
