Suppress cppcheck unknownMacro (#237)

Fast forward to ament/ament_lint#268

This suppresses a defect in `ament_cppcheck` - namely that if a macro is missing, it fails loudly. This is compounded by fact that `ament_cppcheck` does not include all dependent headers, so macros are likely to be missing in the first place.
