Subject: [PATCH] gvc: avoid macro redefinition warning when GVDLL is defined

Without this change, an upcoming commit that defines GVDLL would cause
warnings like this:

C:\Users\magja\graphviz\lib\gvc/gvplugin_loadimage.h(29,1): warning C4005: 'GVPLUGIN_LOADIMAGE_API': macro redefinition [C:\Users\magja\graphviz\build\plugin\gdiplus\gvplugin_gdiplus.vcxproj]
