Add initial memory locality cost awareness to the VM, and include
a basic ACPI SLIT table parser.

For now this just exports the map via sysctl; it'll eventually be useful
to userland when there's more useful NUMA support in -HEAD.

* Add an optional mem_locality map;
* add a mapping function taking from/to domain and returning the
  relative cost, or -1 if it's not available;
* Add a very basic SLIT parser to x86 ACPI.
