Governor is set to ondemand instead of performance out of the box

As I'm testing the image for #4, I see that the CPU governor is set to ondemand after I flashed the image. This shouldn't be the case, as setup/phase1.sh disables the ondemand.service startup file and ros-realtime/linux-real-time-kernel-builder@483090d adds performance to always be enabled? Also, this script should be started on boot (and it is as far as I can tell) should also set it.
Not quite sure what's going on. Will have to double check later. Not the highest priority item right now.

cc: @LanderU since you're testing it as well so it's just a FYI.
