[Piglit] [PATCH 1/2] Fix bogus assertions in builtin uniform test generator.

[Kenneth Graunke]

self.test_rows is measured in a number of 4x4 rectangles, but y is
measured in pixels, so they are not comparable.  The only reason this
doesn't trip is because self.test_rows is currently the number of 4x4
rectangles that can fit in a 250x250 window (62)...and no test has
nearly that many rows of rectangles.

Instead, just assert y fits in the window height.
