Support non DOS/Windows format CSAR manifest file
When recreating the csar manifest file during signature verification, we should use the same newline charater as the original file instead of using the DOS/Windows newline charater to avoid false positive signature verfication failure. Issue-ID: VNFSDK-520 Signed-off-by: Lianhao Lu <lianhao.lu@intel.com> Change-Id: I7bdf0a7f6b46c7def0a92d7ec7f245e268355959
