    git-checkout.sh: handle running git-checkout from a different directory
    
    "$DIR" might not be a full path and it might not have `pwd` as ".."
    directory. So use `cd -` to undo the first `cd` command.
    
    Also, use `basename` to make a symbolic link with a relative path.
    
    This doesn't matter yet but it will when for example the commands to
    clone OVMF is been run from tools/ rather than tools/firmware/.
