sched/fair: Increase weight bits for avg_vruntime
Due to the zero_vruntime patch, the deltas are now a lot smaller and
measurement with kernel-build and hackbench runs show about 45 bits
used.
This ensures avg_vruntime() tracks the full weight range, reducing
numerical artifacts in reweight and the like.
Also, lets keep the paranoid debug code around fow now.
