[FS#1381] busybox: Enable ip_tunnel and ip_neighbor by default

[LEDE Bugs]

A new Flyspray task has been opened.  Details are below. 

User who did this - Jeff Kletsky (jeffsf) 

Attached to Project - OpenWrt/LEDE Project
Summary - busybox: Enable ip_tunnel and ip_neighbor by default
Task Type - Feature Request
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Medium
Priority - Very Low
Reported Version - lede-17.01
Due in Version - Undecided
Due Date - Undecided
Details - For more sophisticated users, ability to manage networking is a key feature of LEDE/OpenWRT.

As configured by default, the ip OBJECTs of tunnel and neighbor are not included. 

As noted in FS#1380 there is no straightforward way to "replace" busybox on a running system with a customized version.

Consider enabling these options by default

Looking at the size of the extracted busybox binary within the package (on the Ubuntu build machine) suggests this will add:
* 4096 bytes for ip_tunnel only
* 8192 bytes for both ip_tunnel and ip_neighbor

"base" diffconfig:

CONFIG_TARGET_ar71xx=y
CONFIG_TARGET_ar71xx_generic=y
CONFIG_TARGET_ar71xx_generic_DEVICE_archer-c7-v2=y
CONFIG_DEVEL=y
CONFIG_BUILD_SUFFIX="just-device"
# CONFIG_DRIVER_11AC_SUPPORT is not set
# CONFIG_PACKAGE_ath10k-firmware-qca988x is not set
# CONFIG_PACKAGE_kmod-ath10k is not set
CONFIG_PACKAGE_kmod-usb-ohci=y

with ip_tunnel added:

CONFIG_TARGET_ar71xx=y
CONFIG_TARGET_ar71xx_generic=y
CONFIG_TARGET_ar71xx_generic_DEVICE_archer-c7-v2=y
CONFIG_DEVEL=y
CONFIG_BUSYBOX_CUSTOM=y
CONFIG_BUILD_SUFFIX="just-device"
CONFIG_BUSYBOX_CONFIG_FEATURE_IP_TUNNEL=y
# CONFIG_DRIVER_11AC_SUPPORT is not set
# CONFIG_PACKAGE_ath10k-firmware-qca988x is not set
# CONFIG_PACKAGE_kmod-ath10k is not set
CONFIG_PACKAGE_kmod-usb-ohci=y

with both added:

CONFIG_TARGET_ar71xx=y
CONFIG_TARGET_ar71xx_generic=y
CONFIG_TARGET_ar71xx_generic_DEVICE_archer-c7-v2=y
CONFIG_DEVEL=y
CONFIG_BUSYBOX_CUSTOM=y

CONFIG_BUSYBOX_CONFIG_FEATURE_IP_NEIGH=y
CONFIG_BUSYBOX_CONFIG_FEATURE_IP_TUNNEL=y
# CONFIG_DRIVER_11AC_SUPPORT is not set

# CONFIG_PACKAGE_kmod-ath10k is not set
