[Piglit] CL FYI: ULP seems broken

I was working on some unit tests for the expm1 builtin cl function tonight,
and I noticed that in piglit-util-cl.c the code to probe float/double
results and check that the result is within a given ulp sees to be treating
the ulp as an actual tolerance instead of as a proper ulp value.
I'll try to see what I can do to fix it, but I wanted to let people know
about it, as fixing the bug may cause a bunch of math rests to start
failing if we have implementations that do not meet the precision
