concat: Reset segment base offset after FLUSH_STOP with reset_time = TRUE

Browse source 
If the reset_time value of a FLUSH_STOP event is set to TRUE, the pipeline
will have the base_time of its elements reset. This means that the concat
element's current_start_offset has to be reset to 0, since it was
calculated with the old base-time in mind.

Only FLUSH_STOP events coming from the active pad are looked at.
