Description: QGtk3Dialog: don't crash on Wayland
Check if it's an X11 window before calling XSetTransientForHint().
No transient parent will be set for GTK+ dialogs on Wayland. That
has to be implemented separately.
Origin: upstream, https://code.qt.io/cgit/qt/qtbase.git/commit/?id=84ea00d47049d882
