GenericExperiment: record output during complete runtime

Browse Source 
Before this change, the GenericExperiment only recorded port 0xe9 output
*after* the fault was injected.  When a fault was injected during the
workload's output loop, the output data before that point in time was
missing, and the experiment outcome was wrongly classified as SDC.

This change moves the logging activation to before the fast-forwarding
step (DatabaseExperiment::cb_before_fast_forward).  It also makes sure the
DatabaseExperiment only clears its own listeners instead of also touching
the SerialOutputLogger's one.
