swaybar: Prioritize hotspot events to bar bindings

This is consistent with i3bar's behaviour, and for example, allows binding a
command to button1, while still being able to click on tray icons or other
zones on the bar's status line which may have their own bindings.

E.g., in Sway, without this commit, this config. makes tray icons unclickable:

    bar {
        # ...
        bindsym button1 exec swaynag -m You_clicked_the_tray._Want_some_help?
    }

But the same configuration in i3 (with i3-nagbar) keeps tray items clickable.
