Try to normalize display numbers again

- Use physical hardware address for where to put rofi
- Switch dunst to output on focused display

Rotom handles displays differently and my TV keeps dropping from the bus
when turned off, changing its display number when powered back on. This
should fix the effects of that, hopefully.
