Corrected tf_getlongsimtime() to match behaviour of other simulators. 

The PLI tf_getlongsimtime() function is a non-standard function provided
for compatibility with some commercial simulators. To match the behaviour
of those simulators, it should return the raw simulation time, not a
scaled time.
