atrace: map 'sync' to linux >= 4.9 fence tracing
Before Linux 4.9, sync was an Android staging driver. In Linux 4.9,
this was upstreamed to be part of the dma-buf framework. Many of the
details changed, including the uapi and tracing events.
Atrace now handles enabling both old and new event systems. But the
events traced differ, so any downstream software that has special-case
handling of sync/fence events will need to be updated.

Test: adb shell atrace --list_categories
