build: SDK/IB reproducible and faster compression
Both IB and SDK now use the same logic for packing. This commit add reproducible multithread compression to the SDK and corrects the file mtime for both. Previously all files where just copied over from the build system, generating random mtimes. Signed-off-by: Paul Spooren <mail@aparcar.org>
