x11: Use the current or last-requested window position when setting the size hint

The move operation is just a no-op to try and force the hint to take effect, so it should use the current window coordinates.

WMs each have their little quirks with that. When you change the
size hints, they get a ConfigureNotify event with the
WM_NORMAL_SIZE_HINTS Atom. They all save the hints then, but they
don't all resize the window right away to enforce the new hints.
Some of them resize only after:
- A user-initiated move or resize
- A code-initiated move or resize
- Hiding & showing window (Unmap & map)
The following move & resize seems to help a lot of WMs that didn't
properly update after the hints were changed. We don't do a
hide/show, because there are supposedly subtle problems with doing so
and transitioning from windowed to fullscreen in Unity.
