Don't ignore SIGPIPE 

By default Python configures SIGPIPE to be SIG_IGN, which means to
ignore the signal. We don't want that as it causes problems when
journald restarts and our log calls start triggering SIGPIPEs.
Instead, we want to allow the SIGPIPE to kill the process so it can
be restarted by systemd.
