build: Use stable file ordering in sysupgrade.tar
The file ordering in the current sysupgrade depends on the order of file in a filesystem. This is often already in a sane (alphabetical order) but this is not always the case. For example, the OpenWrt build servers return a different ordering. This breaks the reproducibility of the sysupgrade tarballs significantly and also resulted in images which cannot be used for upgrades on devices like the OpenMesh A42/A62.
