Need to disable crash reporting service via salt

[larsbergstrom]

You can run:

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.ReportCrash.Root.plist

To disable the crash reporting service (which plays badly with our testing infrastructure), but I'm not sure how to disable it permanently...

#350 backports the launchctl.py module, which lets us handle this via a service.disabled state.

Er, service.dead with - enable: False to make sure it's also not running (not just disabled).

[aneeshusa]

Another, more coarse approach that we can apply now would just be using file.absent to make sure that file doesn't exist (might need to reboot to kill the current process). However, I think this would get affected by rootless/SIP if we upgrade to El Capitan, so I would not prefer this method.
