sparse: MSBuild: add windows include dir to find config.h

An upcoming commit which will include config.h in colorprocs.h would
otherwise cause this error:

C:\Users\magja\graphviz\lib\common\colorprocs.h(13,10): fatal error C1083: Cannot open include file: 'config.h': No such file or directory [C:\Users\magja\graphviz\lib\sparse\gvsparse.vcxproj]
