Fix remaining endian-issue in od(1) 

After setting up qemu and testing od(1) in a Big Endian environment,
I found out that the conditional in the printing function was not
right.
Instead, it's supposed to be way simpler. While at it, we don't need
HOST_BIG_ENDIAN any more. Just set big_endian properly in main()
and be done with it.
