Michael Neuling 2b46b5673c [POWERPC] Fix possible division by zero in scaled time accounting
If we get no user time and no system time allocated since the last
account_system_vtime, the system to user time ratio estimate can end
up dividing by zero.

This was causing a problem noticed by Balbir Singh.
