[roll] Roll fuchsia [tracefs] Striping events across all cpus

This changes the writing of tracefs events to be striped across
all cpus instead of writing all events to cpu 0.

The striping is done by incrementing a counter on each write.

This results in:
 * 18% improvement for the average read, and a 79% for the P90 read.
 * 24% improvement for the average write and 33% for the P90 write.
