Include a better sample JSON dataset in traceline.

Include a better sample JSON dataset in traceline.

The previous startup-off2.json didn't have stack traces.  It was also quite large, it was unfiltered and contained every single system call event.

Include a program to filter a JSON data set to only include events that took a worthwhile amount of time.  This greatly reduces the size of the JSON data.

A new filtered JSON dataset startup-release.json is included, much smaller and with stack traces.

Added an ignore for checkdeps on traceline/.

I probably should have done this originally, but I didn't think too much about
the dataset.  This data is much cleaner and smaller.

Btw, this deletes the old startup-off2.json, but Rietveld isn't showing that.
