cpuload: Fix wrong idle thread load 

When the CPU load monitor is started while already running, then the
idle thread last_times[0] is reset to the last 1 second, rather than
since when the CPU load monitor was last started. The remaining threads
are not impacted, since their last_times[i] is reset to zero here.

This results in the idle thread having a lower than real CPU load, with
the remaining CPU time being wrongly attributed as scheduler load.
