x: fix XIM handling
Do not try to set specific IM method, let the user specify it with
XMODIFIERS.
If the requested method is not available or opening fails, fallback to
the default input handler and register a handler on the new IM server
availability signal.
Do the same when the input server is closed and (re)started.
