firefox: unveil AT SPI2 socket to enable screen reader

https://www.freedesktop.org/wiki/Accessibility/AT-SPI2/

In there is a D-Bus socket used to communicate with tools like
x11/gnome/orca. Use orca(1) -s and tick the 'Speak object under mouse' box
to hear it reading out elements, texts, etc.

I'm new to accessibility features and noticed that browsers wouldn't work
whereas other ports without pledge/unveil would.

Patch is for Firefox and Firefox ESR.
Will check the Chromes next.

Feedback? Objection? OK?
