msgpack/predef/other/endian.h always defines both
MSGPACK_ENDIAN_LITTLE_BYTE and MSGPACK_ENDIAN_BIG_BYTE, but they're
defined to a true or false value depending on whether the system is
little/big endian.
Fix this condition to check the truthiness rather than whether it is
defined, like the other locations this macro is checked.
Closes#403

https://github.com/boostorg/predef.git has been added as a submodule on
external/boost/predef.
In order to avoid macro name conflicts, replaced "BOOST_" with "MSGPACK_"
and "boost/" with "msgpack/" then copy replaced files to include/msgpack.
This process is described in CMakeLists.txt.
Replaced files are included as a part of msgpack-c. So you don't need to
do the converting process each time.
Fixed endian checking logic.
