Jonas Ådahl 4490d4524b xwayland: Handle shutting down without having started
We initialize, but might not start, e.g. when a test case just needs a
backend and doesn't start mutter. When cleaning up, we'll still try to
clean up Xwayland integration, and this commit handles cleaning up
without having made the mess.
