[Piglit] [V2 PATCH 02/12] summary.py: Do not generate comparison pages for single results

[Dylan Baker]

It is absolutely silly to generate pages for fixes, changes, and
regressions when there is only one test result is provided. This still
generates empty pages when two results are provided, because some
developers have expressed a work flow that uses these empty pages.
