KHO is the only dependency of LIVEUPDATE (kernel/liveupdate/Kconfig), so now that riscv has KHO the LUO tests only need the runner to stop rejecting the architecture. Add riscv64 to the CROSS_COMPILE auto-detection list and to the target list of the batch runner as well, matching the existing aarch64/x86_64 entries.
