cbfstool: process cbfs_payload_segment(s) in host byte order

The printing routines of the cbfs_payload_segment assumed the type
could be accessed in host order. Each of the fields need to be
converted to the host order before inspecting the fields. In addition,
this removes all the ntoh*() calls while processing the
cbfs_payload_segment structures.

cbfstool would crash adding entries or just printing entries
containing a payload when -v was passed on the command line.
