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.
