Subject: dev-manual: Created new section to remove packaging requirements

Fixes YOCTO #1706

Added a new subsection to the section that talks about making
a tiny system.  The subject matter fits in with reducing a
kernel image size.

+                Packaging requirements add size to the kernel.
+                One way to reduce the size of the kernel is to remove all the
+                packaging requirements from the image.
+                This reduction includes removing the package manager as well
+                as its dependencies.

+                To eliminate all the packaging requirements for an image,
+                follow these steps:

+                    <listitem><para>Put the following line in your main

+     ROOTFS_POSTPROCESS_COMMAND += "remove_packaging_data_files ;
+                        </literallayout>
+                        For example, the recipe for the
+                        <filename>core-image-minimal</filename> image contains
+                        this line.
+                        You can also add the line to the
