fix compile error when compiling column_predicate-test.cc

 In env : boost 1.57, centos 6.5, it will fail when compiling
 column_predicate-test.cc.
 Specific error messages:
 "gtest-printers.h:245: undefined reference to `std::basic_ostream<char,
 std::char_traits<char>>& boost::operator<< <char,std::char_traits<char>
 ,kudu::ColumnPredicate>>(std::basic_ostream<char,
 std::char_traits<char>>&, boost::optional<kudu::ColumnPredicate> const&)`"

 Adding optional_io.hpp into column_predicate.h get another compile error:
 "operator<<: cannot bind lvalue to 'std::basic_ostream<char>&&'"
 write a boost:operator<< in column_predicate.c , compile succeed.
