[PATCH qemu-server] cpu models: only include custom models on x86_64

[Arthur Bied-Charreton <a.bied-charreton@proxmox.com>]

The custom CPU models config does not currently expose a way to specify
an arch and it defaults to x86_64.

Only include custom models if $arch is set to x86_64 to prevent listing
x86_64-only custom models in the CPU model selector for arm VMs.
