In case wlroots is not being compiled with XWayland support, we will not have an xwayland surface in our roots view. While we make sure to pay attention to that in some places, we are not being consistent and try to access the xwayland surface in other places. Obviously, this leads to a compiler error due to the field not being present. Fix the issue by sprinkling in a few additional ifdefs where required.
