[Piglit] [PATCH] tests/quick.py: reduce the number of vs_in tests in quick.py

[Dylan Baker]

There are 18000 of these tests, quick.py has 53000 tests, which is 34%
of the total tests. That's just too many for quick.py.

This patch takes the somewhat naive approach of just filtering out 80%
of those tests from quick.py, which reduces the total number of tests to
38000, which makes a pretty big dent in the amount of time it takes to
run quick.py. The approach is deterministic, but random.

+"""A quicker profile than all.

+This profile filters out a number of very slow tests, and tests that are very
+exhaustively tested, since they add a good deal of runtime to piglit.
+
+There are 18000+ auto-generated tests that are exhaustive, but for quick.py we
+don't want that level of exhaustiveness, so this filter removes 80% in a random
+(but deterministic) way.
