Daniel P. Berrangé 0169f5ecde tests: add host CPU data files for validating die_id
Only Cascadelake-AP CPUs appear to report "die_id" values != 0 on Linux
right now - AMD EPYC's don't report "die_id" (at least with Fedora 31
kernel). Lacking access to Cascadelake-AP CPUs, this test data was from
a Fedora 31 QEMU guest launched with

 -cpu qemu64 -smp sockets=2,dies=3,cores=2,threads=1

Ideally we'd replace this data with some from a real machine reporting
"die_id", to ensure we're not mislead by QEMU's impl.
