tests/functional/test_tuxrun: Restrict to TCG

The tuxrun tests specify the cortex-a57 CPU; this doesn't work on a
KVM-only QEMU build, where the default accelerator is KVM but KVM
doesn't support that CPU type.  Restrict the test to TCG, to avoid
failures on KVM-only AArch64 builds:
        Output: qemu-system-aarch64: kvm_init_vcpu: kvm_arch_init_vcpu failed (0): Invalid argument
