perf evlist: Remove stale mmap read for backward

Browse source

perf_evlist__mmap_read_catchup() and perf_evlist__mmap_read_backward()
are only for overwrite mode.

But they read the evlist->mmap buffer which is for non-overwrite mode.

It did not bring any serious problem yet, because there is no one use
it.

Remove the unused interfaces.
