trace_processor: fix up sqlstats table (and time reported in shell)

Make the new iterator API work with the sqlstats table by splitting
the time_ended column into a "first next" column (which reports the
time to the first Next call on the iterator) and the actual end column
when the iterator is destroyed.

Also fix a subtle issue in trace processor interactive mode reporting
negative execution time.
