cbfstool: provide structure to linux payload builder

This change started with tracking down a bug where the trampoline
    size was not being taken into account for sizing the output buffer
    leading to a heap corruption.  I was having a hard time keeping
    track of what num_segments actually tracked as well as what parts
    were being placed in the output buffer. Here's my attempt at
    hopefully providing more clarity.

This change doesn't crash when adding a bzImage:
    $ dd if=/dev/zero of=bb.bin bs=64 count=1
    $ ./cbfstool tmp.rom create -s 4M -B bb.bin -m x86 -a 64
    $ ./cbfstool tmp.rom add-payload -f ~/Downloads/bzImage -C "1" -n
    "fallback"/payload
