gconstructor.h: Ensure [c|d]tor prototypes are present for MSVC

Browse Source 
This way, the generated GResource code won't choke if no prototypes are found
when being built by clang-cl, which also goes the _MSC_VER >= 1500 route.

Fixes clang-cl build of generated GResources code when building the appstream
git checkout, which supported Windows recently, as the build there demands
'-Werror,-Wmissing-prototypes'.
