    MetaIdleMonitorNative: initialize last event timestamp
    
    If this isn't initialized and an idle watch gets instanced before
    meta_idle_monitor_native_reset_idletime() gets called, that idle watch
    would get triggered as soon as we hit the main loop.
    
    This was causing gnome-session to go into idle mode at session start
    thus making gnome-shell lock the screen.
    
    In the past this bug was being masked by either logind emiting
    session active signals or a stray input event making it through at
    startup.
