RFR: JDK-8148548: [Linux/Solaris] debuginfo and fastdebuginfo bundle contains demo info

[Erik Joelsson]

Hello,

When introducing the new bundle targets in the top level makefiles, I 
accidentally added the demo debuginfo files in the jdk symbols bundle. 
This patch filters out any demo and sample files from the symbols bundle.
