drm/syncobj: Extend EXPORT_SYNC_FILE for timeline syncobjs
Add support for exporting a dma_fence fd for a specific point on a
timeline. This is needed for vtest/vpipe[1][2] to implement timeline
syncobj support, as it needs a way to turn a point on a timeline back
into a dma_fence fd. It also closes an odd omission from the syncobj
UAPI.
