tests/qtest: Skip Aarch64 VMapple machine

First, the VMapple machine only works with the ARM 'host' CPU
type, which isn't accepted for QTest:

  $ qemu-system-aarch64 -M vmapple -accel qtest
  qemu-system-aarch64: The 'host' CPU type can only be used with KVM or HVF

Second, the QTest framework expects machines to be createable
without specifying optional arguments, however the VMapple
machine requires few of them:

  $ qemu-system-aarch64 -M vmapple -accel qtest
  qemu-system-aarch64: No firmware specified

  $ qemu-system-aarch64 -M vmapple -accel qtest -bios /dev/null
  qemu-system-aarch64: No AUX device. Please specify one as pflash drive.

Restrict this machine with QTest so we can at least run check-qtest,
otherwise we get:

  $ make check-qtest-aarch64
  qemu-system-aarch64: The 'host' CPU type can only be used with KVM or HVF
  Broken pipe
  ../tests/qtest/libqtest.c:199: kill_qemu() tried to terminate QEMU process but encountered exit status 1 (expected 0)
