[PATCH-for-9.2? 1/2] tests/functional/test_version: Use QTest accelerator

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

When testing with a HVF-only binary, we get:

   3/12 qemu:func-quick+func-aarch64 / func-aarch64-version                                      ERROR            0.29s   exit status 1
  stderr:
  Traceback (most recent call last):
    File "tests/functional/test_version.py", line 22, in test_qmp_human_info_version
      self.vm.launch()
    File "machine/machine.py", line 461, in launch
      raise VMLaunchFailure(
  qemu.machine.machine.VMLaunchFailure: ConnectError: Failed to establish session: EOFError
      Exit code: 1
      Command: build/qemu-system-aarch64 -display none -vga none -chardev socket,id=mon,fd=5 -mon chardev=mon,mode=control -machine none -nodefaults
      Output: qemu-system-aarch64: No accelerator selected and no default accelerator available

Explicit the QTest accelerator to be able to run the HMP command.
