Review request: 2223156 Removal of lzma and upx from JDK7u repo

[David Katleman]

Please review this change, removal of lzma and upx from the open repos 
of JDK7u

     http://cr.openjdk.java.net/~katleman/2223156/webrev.root.03/
     http://cr.openjdk.java.net/~katleman/2223156/webrev.jdk.03/

Usage of lzma and upx have been completely internalized into the closed 
jdk repos.

         Thanks
                 Dave
