Add script to create kconfig fragment; defaults to busybox fragment if
only one config is specified (compares to package/busybox/busybox.config).

+# DESCRIPTION:
+#     Creates a fragment by comparing two kconfigs. Default usage creates a
+#       busybox fragment, however providing two config files will override this.
+#
+#     Required arguments:
+#       $1 - config #1. This is generally the new one created
+#
+#     Optional arguments:
+#       $2 - config #2: The configuration file to compare against. If none
+#            supplied, will compare against package/busybox/busybox.config
