    oe-selftest: crosstap: add tests for crosstap script
    
    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.
