[PATCH v3 08/12] test: dm: dsa, eth: disable tests when CONFIG_NET_LWIP=y

[Jerome Forissier]

Some sandbox tests make strong assumptions on how the network stack is
implemented. For example, the ping tests assume that ARP resolution
occurs upon sending out the ICMP packet. This is not always the case
with the lwIP stack which can cache ARP information.
Therefore, disable these tests when CONFIG_NET_LWIP is enabled.
