bitbake: knotty, uihelper: Remove running_pids and lastpids

* lastpids has not been used for almost 10 years.
* There is no longer any need to use running_pids to keep track of the
  order the pids in running_tasks were added as dicts are guaranteed to
  remember the insertion order since Python 3.7.
