cbfstool: make fmap search more strict

Since fmap doesn't come with a checksum, we resort to a number of
    heuristics to determine if a given location hosts an fmap (instead of
    another data structure that happens to store the fmap magic string at
    the right location).

The version test is particularly effective against strings containing
    the magic (which either terminate with 0, or have some other ASCII data,
    but rarely a '\001' byte inside the string).
