ACPI/unit-test: Add a testcase for RAM allocation in numa node 

As QEMU supports the memory-less node, it is possible that there is
no RAM in the first numa node(also be called as node0). eg:
  ... \
  -m 128,slots=3,maxmem=1G \
  -numa node -numa node,mem=128M \

But, this makes it hard for QEMU to build a known-to-work ACPI SRAT
table. Only fixing it is not enough.

Add a testcase for this situation to make sure the ACPI table is
correct for guest.
