i3bar: Only configure tray on own outputs

Patch status: needinfo

Patch by Tony Crisci

Long description:

If the config specifies a `tray_output` not in the list of outputs over
which this bar will span, do not initialize a tray for the bar.

Fix former behavior, which was to initialize the tray without showing
the icons.
