Instrument/gem5power: Rename timestamp channel to match new API

Browse Source 
To conform with the new DerivedMeasuements API the "sim_seconds" channel
has been renamed to "timestamp" so that it can be identified in post
processing. As "sim_seconds" needs to be extracted from the gem5
statistics file, an addional mapping has been added to support this.
