watchdog is unreliable in some circumstances

I encountered this issue running the puppet-training.ova vm through VirtualBox with a bridged network interface on the Puppet internal wifi. Session would end after ~30 seconds, suggesting that the watchdog heartbeat check was never successful. The problem was resolved by removing the watchdog line from the systemd service file.

I suspect that the spawned watchdog thread is not inheriting the systemd environment. Systemd is killing it because it gets no notifications. That's likely an upstream systemd change, too.
