When building with clang with the --without-tcmalloc flag set, the -fno-builtin flag is not used, and clang can then detect that the integer version of abs(), apparently the C version, is being used on a floating point value in traffic_gen.cc. This change takes clang's suggestion to use std::abs instead, and also includes a header file which will provide it.
