FIXME: disable additional_event_mask in NetworkInterface::begin()

This change addresses an issue where combining additional_event_mask with
NET_EVENT_IPV4_ADDR_ADD in the net_mgmt_event_wait_on_iface function
caused unexpected behavior due to Zephyr's internal event handling.

By isolating the wait to only NET_EVENT_IPV4_ADDR_ADD, we ensure that
the function behaves as intended. A more robust solution involving
semaphores and multiple event registrations will be implemented in the
future.
