[Piglit] [PATCH] glsl-fs-user-varying-ff: ignore probing result

[Vadim Girlin]

The test is not very reliable, because it checks if the result is
"undefined" by comparing it with some constant. "undefined" value
_probably_ will not be equal, but it still could be equal.

Fixes random fails with r600g.

Btw, I think I don't have commit access for piglit, if it's not the same as for
mesa. If so, could somebody please push this patch (if there are no objections,
of course).
