vtime: Make vtime_account_system() irqsafe
vtime_account_system() currently has only one caller with
vtime_account() which is irq safe.
Now we are going to call it from other places like kvm where
irqs are not always disabled by the time we account the cputime.
So let's make it irqsafe. The arch implementation part is now
prefixed with "__".
vtime_account_idle() arch implementation is prefixed accordingly
to stay consistent.
