Subject: [PATCH] NovaEvacuate: Avoid initial useless message on stderr

When no evacuation has been done yet, we're spamming syslog with:

  Could not query value of evacuate: attribute does not exist

So let's just filter this out, since it's known to be expected on

initial setup.

As this requires a bashism, also move the script to use bash.
