            Sanitize upstream tarball to strip non-free blobs before packaging

The upstream tarball ships prebuilt libdpa_elf blobs that must not
appear in the source RPM at all, not even transiently as removing them
in %prep would allow. Add generate-tarball.sh to repack the upstream
release with those blobs stripped, and switch Source0 to the resulting
mstflint-4.37.0-1.1.free.tar.gz.
