This moves piglit-run and piglit-resume main() functions to
framework.programs.run as run() and resume() respectively, and moves
piglit-summary-* to framework.programs.summary. It then creates
compatibility wrappers as piglit-*.py for the functions.

This is groundwork for a combined piglit interface. The original files
could not be imported directly since they have dash (-) in their name,
and python considers dash an illegal character for function, class, and
modules names, and python would raise an ImportError when attempting to
import one of them.
