setup.py: do not add invalid header locations

This piece of code incorrectly adds /usr/include to
self.compiler.include_dirs, and results in the following invalid
compilation line:

/home/thomas/projets/buildroot/output/host/usr/bin/arm-none-linux-gnueabi-gcc -fPIC \
  -fno-strict-aliasing -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 \
  -pipe -Os -DNDEBUG -g -O3 -Wall -Wstrict-prototypes \
  -I/usr/include -I. -IInclude -I./Include \
  -I/home/thomas/projets/buildroot/output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr/include \
  -I/home/thomas/projets/buildroot/output/build/python-2.7.6/Include \
  -I/home/thomas/projets/buildroot/output/build/python-2.7.6 \
  -c /home/thomas/projets/buildroot/output/build/python-2.7.6/Modules/mathmodule.c \
  -o build/temp.linux2-arm-2.7/home/thomas/projets/buildroot/output/build/python-2.7.6/Modules/mathmodule.o
cc1: warning: include location "/usr/include" is unsafe for cross-compilation [-Wpoison-system-directories]
