[ceph-nautilus] Fix fuzzer test on big-endian systems

Browse source 
Currently, the test_expand_random_binary test fails on big-endian
systems.  It turns out that this is because the special_random
routine in RepeatExpandingFormatter uses struct.pack in a manner
where the returned byte sequence depends on host byte order.

Fixed this to enforce the same output across platforms.
