cpu: Use std::abs() in traffic_gen.cc.

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.
