Disable accessibility

Accessibility prevents sysprof from working reliably, so disable
it. Specifically, it

- causes large amounts of time to be spent in sysprof itself
  whenever the label is updated.

- sometimes hangs at shutdown

- does long-running roundtrip requests that prevents
  reading the event buffers, resulting in lost events.
