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.
