sched/fair: trace energy_diff for non boosted tasks
In systems where SchedTune is enabled, we do not report energy diff for non
boosted tasks. Let's fix this by always genereting an energy_diff event where
however:
nrg.delta = 0, since we skip energy normalization
payoff = nrg.diff, since the payoff is defined just by the energy difference
