bitbake: server/process: Avoid tracebacks at exit

In theory this should have been worked around but is still occurring. Add
it to the list of things to ignore when bitbake is shutting down.

Traceback (most recent call last):
  File "/usr/lib64/python3.9/threading.py", line 973, in _bootstrap_inner
    self.run()
  File "/home/pokybuild/yocto-worker/oe-selftest-fedora/build/bitbake/lib/bb/server/process.py", line 698, in startCallbackHandler
    event = self.reader.get()
  File "/home/pokybuild/yocto-worker/oe-selftest-fedora/build/bitbake/lib/bb/server/process.py", line 722, in get
    res = self.reader.recv_bytes()
  File "/usr/lib64/python3.9/multiprocessing/connection.py", line 221, in recv_bytes
    buf = self._recv_bytes(maxlength)
  File "/usr/lib64/python3.9/multiprocessing/connection.py", line 426, in _recv_bytes
    return self._recv(size)
  File "/usr/lib64/python3.9/multiprocessing/connection.py", line 384, in _recv
    chunk = read(handle, remaining)
TypeError: an integer is required (got type NoneType)'
