perf jevents: Free the sys_event_tables list after processing entries

Browse Source 
The compiler reports that free_sys_event_tables() is dead code.

But according to the semantics, the "LIST_HEAD(sys_event_tables)" should
also be released, just like we do with 'arch_std_events' in main().

Fixes: e9d32c1bf0 ("perf vendor events: Add support for arch standard events")
