CPack handle symlinks in CPACK_INSTALLED_DIRECTORIES fix for bug5430 

The proposed solution is to avoid to CopyIfDifferent any links
found in CPACK_INSTALLED_DIRECTORIES but memorize them instead
then at the end of the processing for each dir do re-create the
link in the installed tree.
Current patch should work if the link are "local" to the directory.
