Bug 1244446 - Run automation build steps before postflight_all. r=gps,r=ted Killing the sccache background daemon is part of postflight_all, but in the current setup, postflight_all happens at the end of a "normal" build, but we run automation build steps after that. What happens then is that more compilations happen (gtests), which start sccache again, but there's nothing to kill sccache again once this is all done. Now that the OSX universal builds postflight is gone, it is not necessary for postflight_all to happen before the automation build steps. So ensure postflight_all scripts happen last. The downside of this change is that this now prevents sccache.log from being uploaded, but we should probably send processed data to the graph server instead.
