(X11) Optimize x11_update_title - it was previously calling XChangeProperty

Browse Source 
at regular intervals even when the title output for the window title had not
changed at all, now we compare it properly against the last set title, and
only if it has changed will we make the call to XChangeProperty. Also, do
away with strlen(title) calculation and use return value of
video_driver_get_window_title instead
