meta-skeleton: Add busybox config fragment example
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.
