Tar will automatically record the user/group ID and name for
files/directories. This reduces the reproducibility of the sysupgrade.tar
because most of the people don't use the same username as the OpenWrt
buildserver.

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.

Now that the "sysupgrade-nand" step is used by non-NAND targets as well,
rename it to "sysupgrade-tar" to make it more generic.
