[PATCH] toaster: log ProcessLookupError in test_runbuilds

This repeatably fails:

Exception in thread Thread-2:
Traceback (most recent call last):
  File "/usr/lib/python3.10/threading.py", line 1016, in _bootstrap_inner
    self.run()
  File ".../poky/bitbake/lib/toaster/tests/commands/test_runbuilds.py", line 39, in run
    os.kill(int(pid), signal.SIGTERM)
ProcessLookupError: [Errno 3] No such process

Rather than have a hard error, add logging and output as a warning.
