Bug 1287938 - Make ts_paint use the parent process start time and first paint info in calculations. r=jmaher

Browse Source 
Instead of checking for the paint time of the tspaint_test.html content,
we're now measuring the delta between process start and first paint as
reported by the parent process's startup info.
