    win32: Fix GDBusDaemon build when glib is built as a static lib
    
    This makes sure not to ifdef _g_io_win32_get_module() out when glib is
    built as a static lib, and also fixes it to work when DllMain isn't
    available.
    
    The implementation uses GetModuleHandleEx() which is only available on
    Windows XP and later, so this commit effectively drops the Windows 2000
    support in glib. Earlier commit 731b4699 already took care of defining
    _WIN32_WINNT to support the Windows XP API.
