bitbake: bitbake-worker: Handle SIGKILL of parent gracefully

If we SIGKILL cooker (the parent process), ensure the worker notices
and shuts down gracefully. To do this:

* trigger the sigterm handler if the parent exits
* ensure broken pipe writes don't trigger backtraces which interfer with
  other exit work
* notice if our command pipe is broken due to EOF and sigterm if so
