perf trace: Free strings in trace__parse_events_option()
ASan reports several memory leaks running:
# perf test "88: Check open filename arg using perf trace + vfs_getname"
The fourth of these leaks is related to some strings never being freed
in trace__parse_events_option.
This patch adds the missing frees.
