cbfstool: add code to serialize the header using the new xdr functions

This change adds a header serialization function. Programmers can thus just
    set up a header as needed, without worrying about forgetting if and how to
    use the [hn]to[hn]* functions.

In the long term, we will work to remove swab.h, i.e. we need to get to the
    point where programmers don't have to try to remember [hn]to[nh]* and where
    it goes. To date, even the best programmers we have have made an error with
    those functions, and those errors have persisted for 6 or 7 years now. It's
    very easy to make that mistake.

BUG=None
    TEST=Build a peppy image and verify that it's bit for bit the same. All
         chromebooks use this code and build and boot correctly.
    BRANCH=None
