xwayland: Do not resize when running fullscreen 

When running fullscreen, if an X11 client has changed the resolution,
Xwayland is using a viewport to emulate the expected resolution.

When changing focus, the Wayland compositor will send a configure event
with the actual surface size, not the size of the emulated XRandR
resolution.

As a result, changing focus while XRandR emulation (and hence the
viewport) is active in Xwayland will revert the resolution to the actual
output size, defeating the XRandR emulation.

To avoid that issue, only change the size when not running fullscreen.
