kvm: selftests: conditionally build vm_xsave_req_perm() 

vm_xsave_req_perm() is currently defined and used by x86_64 only.
Make it compiled into vm_create_with_vcpus() only when on x86_64
machines. Otherwise, it would cause linkage errors, e.g. on s390x.

Fixes: 415a3c33e8 ("kvm: selftests: Add support for KVM_CAP_XSAVE2")
