Subject: remove trailing \r in xboard output

remove trailing \r in xboard output

there is an annoying carriage return (displayed as ^M) at the end of the PV in the engine-output window, not
only with Fairy-Max, but also with UCI engine running under Polyglot. This patch replaces the trailing CR that Linux programs send after the PV line y a space.
