[Piglit] [PATCH] generated_tests/builtin_function.py: hide RuntimeWarnings

[baker.dylan.c at gmail.com]

From: Dylan Baker <baker.dylan.c at gmail.com>

These warnings are expected, it's better to hide expected warnings and
provide a comment about them being expected than to have them clutter
the output of the build system.

Signed-off-by: Dylan Baker <dylanx.c.baker at intel.com>

The fact that these are expected is based off of a comment Paul Berry
made to me in the past, not of my personal knowledge of the generators.
Since he wrote this module I expect that he knew what he was talking
about.
