QA team were testing crosstap script manually. Add automated tests and systemtap file to test that crosstap script will instructs SystemTap to print hello world in qemu. This test will first built core-image-minimal image with tools-profile & ssh-server-openssh features and build systemtap-native on the host machine. Finally this test will boot the image with qemu and then execute crosstap script to print hello world on qemu.
