perf script: Fix event ordering settings to work with older kernels
If we don't use .ordering_requires_timestamps we'll end up trying to order events with no timestamps when running on older kernels. Problem introduced in eac23d1c. After the last three fixes, perf scripting is back working, tested with new perf userspace on old and new (with sample_id_all) kernels.
