cbfstool: Make endian detection functions to work without prior setup.
The 'host_bigendian' variable (and functions relying on it like ntohl/htonl)
requires host detection by calling static which_endian() first -- which may be
easily forgotten by developers. It's now a public function in common.c and
doesn't need initialization anymore.
