mem-cache,python: Allow custom TLB and events in each prefetcher.
The `BasePrefetcher` python class had members `_events` and `_tlbs`
defined as lists, meaning that any call to `list.append` on them would
affect `_events` and `_tlbs` for all prefetchers, not just the calling
object. This change redefines them as `None` by default and sets the
value to a per-object empty list before inserting the first element.
