Userland et al: Pledge sigaction when needed

* In some cases, we can first call sigaction()/signal(), then *not* pledge
  sigaction.
* In other cases, we pledge sigaction at first, call sigaction()/signal()
  second, then pledge again, this time without sigaction.
* In yet other cases, we keep the sigaction pledge. I suppose these could all be
  migrated to drop it or not pledge it at all, if somebody is interested in
  doing that.
