bitbake: knotty/uihelper: Switch from pids to tids for Task event management

We've seen cases where a task can execute with a given pid, complete
and a new task can start using the same pid before the UI handler has
had time to adapt.

Traceback (most recent call last):
  File "/home/pokybuild/yocto-worker/qemux86-alt/build/bitbake/lib/bb/ui/knotty.py", line 484, in main
    helper.eventHandler(event)
  File "/home/pokybuild/yocto-worker/qemux86-alt/build/bitbake/lib/bb/ui/uihelper.py", line 30, in eventHandler
    del self.running_tasks[event.pid]
KeyError: 13490

This means using pids to match up events on the UI side is a bad
idea. Change the code to use task ids instead. There is a small
amount of fuzzy matching for the progress information since there
is no task information there and we don't want the overhead of a task
ID in every event, however since pid reuse is unlikely, we can live
with a progress bar not quite working properly in a corner case like
this.
