plugin/gd: define GVDLL to ensure correct storage-class attributes

An upcoming commit will change the storage-class attributes to be
controlled by the GVDLL symbol in gvplugin_gd.c.

Without this change, errors like this would occur:

EXEC : error : failed to resolve gvplugin_gd_LTX_library in C:\Users\magja\graphviz\Debug\Graphviz\bin\gvplugin_gd.dll
