base-files: sysupgrade-tar: allow separated kernel/rootfs ubi

Browse Source 
There are some devices putting kernel and rootfs on separated
ubi volumes. To make OpenWrt compatible with their bootloader,
we need to put kernel and rootfs into separated ubi volumes.
Add support for CI_KERN_UBIPART and CI_ROOT_UBIPART for this
situation.
