charset="utf-8" kvm_dirty_ring_supported() only checks whether the dirty ring support is available on the x86 host, but it ignores whether the target QEMU architecture is x86 or not. Thus the test_vcpu_dirty_limit() test currently fails with the assert((strcmp(arch, "x86_64") =3D=3D 0)) statement in dirtylimit_start_vm() if the users run e.g. "make check-qtest-aarch64" on their x86 host. Fix it by only executing the tests when we're running with a x86_64 target QEMU binary with KVM.
