Upgrade: system upgrade package is added

For upgrade of RW partition, offline system update function of
systemd is activated. Update scripts for each packages should
be under the upgrade/update-script, and new files for update
version should be under the upgrade/data.

* The update scripts are executed alphabetically (ref: man ls).
To specify the execution order explicitly, numeric prefix
can be used such as:
 00.first.patch.sh, 01.second.patch.sh
