[PATCH 2/2 v3] meta-skeleton: Add busybox config fragment example

[Saul Wold]

This shows an example of the config fragment support that
both the linux-yocto and busybox recipes use. This example
is specific to busybox.

By adding busybox CONFIG options into a .cfg file and then
adding that .cfg file to SRC_URI the merge_config.sh script will
correctly handle these CONFIG options during the do_configure task.
The merge_config.sh script uses a last-in wins method.

For more details about this, see the Kernel Development Manual Section 2.2.3
http://www.yoctoproject.org/docs/current/kernel-dev/kernel-dev.html#changing-the-configuration

v2: fixed FILESEXTRAPATHS
v3: Fixed kconfig line and added comments
