    cbfstool: Initialize contents of linux_params to 0
    
    When linux is used as payload, the parameters to the kernel are build
    when cbfstool includes bzImage into the image. Since not all
    parameters are used, the unused will stay uninitialized.
    There is a chance, that the uninitialized parameters contain
    random values. That in turn can lead to early kernel panic.
    To avoid it, initialize all parameters with 0 at the beginning.
    The ones that are used will be set up as needed and the rest
    will contain 0 for sure. This way, kernel can deal with the
    provided parameter list the right way.
