Fix dependency tree so that lwip doesn't depend on any specific network interface component. Network interface drivers shall depend on esp_netif. esp_netif shall depend on lwip (but not on any specific interface driver) -- it optionally depends on vfs and esp_eth (need ethernet header for L2/bridge mode)
