slave: emit user-notifications before dup:ing stdin/stdout/stderr

Browse source 
Since we need to restore the status flags anyway, there's nothing to
gain from emitting the user notifications after dup:ing the pts file
descriptor.

On the other hand, emitting user notifications *before* dup:ing means
we can still print error messages for e.g. write(3) errors.
