[Piglit] Cleanup tesselation generators

[Dylan Baker]

Since I have review on some of them, and they've been on the list a
while. I am planning to push patches 1-16 shortly. These are just small
cleanup patches (comments, formatting changes, using six for a few
functions, using textwrap, etc).

None of these result in functional changes or in any change to the
output of the generators, and they have been tested to keep working, and
to produce the same output before and after.
