dev-manual: Updated the example to identify GPL files.

Fixes [YOCTO #10323]

In the Providing the Source Code section, I replaced the 3-line
code example that returns GPL files.  The bits I put in are a
script that does the trick.  The 3-line example was not working.

                 Let us assume you are only concerned with GPL code as
-                identified with the following:
+                identified by running the following script:
                 <literallayout class='monospaced'>
-     $ cd poky/build/tmp/deploy/sources
-     $ mkdir ~/gpl_source_release
-     $ for dir in */*GPL*; do cp -r $dir ~/gpl_source_release; done
-                </literallayout>

+     src_release_dir="source-release"
+     mkdir -p $src_release_dir

+           if [ $numfiles -gt 1 ]; then

                 At this point, you could create a tarball from the
                 <filename>gpl_source_release</filename> directory and
                 provide that to the end user.
