feat(xCAT-server): add the riscv64 Ubuntu package lists

24.04 and 26.04 had no riscv64 package list, so a diskless image or an install
for the architecture fell back to the generic list and reached debootstrap
without a kernel or the tools the boot scripts call.

The lists hold the same packages as their x86_64 counterparts. Every one of
them is published for riscv64 in noble and resolute, main or universe.
