intel/eu: print bytes instead of 32 bit hex value
INTEL_DEBUG=hex prints 32 bit hex value and due to endianness of CPU
byte order is reversed. In order to disassemble binary files, print
each byte instead of 32 bit hex value.
v2: Print blank spaces in order to vertically align output of compacted
instructions hex value with uncompacted instructions hex value.
(Matt Turner)
v3: Fix line wrap at correct length
