vbo: avoid including wingdi.h on win32

On Windows, main/glheader.h ends up including windows.h which in turn
includes wingdi.h unless the NOGDI macro is defined. And wingdi.h
defines a macro called "ERROR", which we end up redefining below.

To avoid a warning on the redefinition, we can define NOGDI to prevent
wingdi.h from implicitly being included.
