vtime: Always scale generic vtime accounting results
The cputime accounting in full dynticks can be a subtle mixup of CPUs using tick based accounting and others using generic vtime. As long as the tick can have a share on producing these stats, we want to scale the result against CFS precise accounting as the tick can miss some task hiding between the periodic interrupt.
