Now, that LUO and KHO both live under kernel/liveupdate, it makes sense to also move the kho debugfs files to liveupdate/ in order to keep current and upcoming LUO/KHO features organized.
The old names: /sys/kernel/debug/kho/out/ /sys/kernel/debug/kho/in/
The new names: /sys/kernel/debug/liveupdate/kho_out/ /sys/kernel/debug/liveupdate/kho_in/
Also, export the liveupdate_debufs_root, so future LUO selftests, kexec telemtry, and other users could use it as well.
