Fixed a case of over-counting in RemoteWallClockTime. Sequence of events that I believe caused the observed overcounting: 1. Job is running. 2. Power cut. 3. Schedd updates RemoteWallClockTime from WallClockCheckpoint. 4. CkptWallClock() is called before new shadow starts and updates    WallClockCheckpoint based on old shadow's birthdate. 5. Another power cut. Goto 3.
