follow dpkg and xz and use CRC64 for xz compression
dpkg switched from CRC32 to CRC64 in 777915108d9d36d022dc4fc4151a615fc95e5032 with the message: | This is the default CRC used by the xz command-line tool, align with | it and switch from CRC32 to CRC64. It should provide slightly better | detection against damaged data, at a negligible speed difference.
