Update tarball generation script in preparation for PR3681/RH1656677 SunEC changes. Use remove-intree-libraries.sh to remove the remaining SunEC code for now. Fix PR1983 SunEC patch so that ecc_impl.h is patched rather than added Add missing RH1022017 patch to reduce curves reported by SSL to those we support. Remove RH1648995; fixed upstream
