Before this commit, sysupgrade saved the settings backup data to
the area following rootfs even though the device has an actual
rootfs_data partition. The backup data was completely ignored on
the following boot, but since rootfs_data was not being cleared
during sysupgrade, the issue was not noticed earlier.
Note that this commit changes the filesystem of rootfs_data from
ext4 to F2FS (if OEM partitioning is used).
