make adspd trusted across multi-user boundaries.

f247d45f8881b5987b5599193028156264498565 was an incomplete change.
In addition to marking /dev/socket/adspdsock as trusted across
multi-user boundaries, we also need to mark the adspd process itself
as trusted across multiuser boundaries.

Maybe fix bug: 20951546
