The output of 'find' depends on the directory entries, and is not ordered. As a consequence, the cpio archive is not reproducible. Fix that by sorting the output of find. Use the 'C' locale to enforce reproducibility that does not depend on the locale. The command line is now pretty long, so we wrap it.

MORIN <yann.morin.1998@free.fr> (cherry picked from commit 4728fdd4c06be07883e59eeb148c86cb74e10d73) Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
