Remove duplication of directories searched for include files, which may not be harmful but makes build messages ugly. Problem scenario: 1. SWIG_PY_INCLUDES includes SWIG_INCLUDES. SWIG_RB_COMPILE includes SWIG_RB_INCLUDES, which includes SWIG_INCLUDES. 2. COMPILE_PY_WRAPPER includes both of SWIG_PY_INCLUDES and SWIG_INCLUDES. COMPILE_SWIG_RB includes SWIG_RB_COMPILE and SWIG_RB_INCLUDES. COMPILE_RB_WRAPPER includes SWIG_RB_COMPILE, SWIG_INCLUDES, and SWIG_RB_INCLUDES.
