This fixes occasional 9p test failures when running 'make check -jN' if QEMU was compiled for multiple target architectures, because the individual architecture's test suites would run in parallel and interfere with each other's data as the test directory was previously hard coded and hence the same directory was used by all of them simultaniously. This also requires a change how the test directory is created and deleted: As the test path is now randomized and virtio_9p_register_nodes() being called in a somewhat undeterministic way, that's no longer an appropriate place to create and remove the test directory. Use a constructor and destructor function for creating and removing the test directory instead. Unfortunately libqos currently does not support setup/teardown callbacks to handle this more cleanly.
