test: Detect Intel Sapphire Rapids as CPU model

We have to skip the snapshot restore performance test on Intel Sapphire
Rappids for now, since a new KVM API (KVM_GET_XSAVE2) that has not been
supported yet in rust-vmm kvm-ioctls, although it will be supported
soon. To skip on Intel Sapphire Rapids, the python testing framework has
to be able to detect Intel Sapphire Rapids.
