[PATCH 2/3] tests/qtest/vnc-display-test: Use the 'none' machine

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

If we don't specify any machine, an architecture default
might be picked. But some architectures don't provide any
default, such ARM:

  $ make check-qtest-aarch64
  ...
  19/20 qemu:qtest+qtest-aarch64 / qtest-aarch64/vnc-display-test
  qemu-system-aarch64: No machine specified, and there is no default

Since we don't need any particular machine to run this VNC
test, use the 'none' machine.
