[PATCH] tools/virtio: virtio_test -h,--help should return directly

[Rong Tao]

From: Rong Tao <rongtao@xxxxxxxx>

When we get help information, we should return directly, and we should not
execute test cases. At the same time, the code indentation issue was fixed
and virtio-trace/trace-agent was added to .gitignore.
