Subject: [PATCH 53/83] perf tests: Set evlist of test__basic_mmap() to !overwrite

From: Wang Nan <wangnan0@...wei.com>

In this test, a large ring buffer is required so all events can feed
into, so overwrite or not is meaningless.

Change to !overwrite so following commits can remove this argument.
