[Piglit] [PATCH] shader_runner: Use %u in "probe atomic counter" scanf calls.

[Kenneth Graunke]

We're trying to compare two unsigned values, so we should use %u.

For whatever reason, using %d instead of %u causes
tests/spec/arb_compute_shader/execution/atomic-counter.shader_test
to read 2147483647 instead of 4294966784 for the expected value
which is written directly in the [test] script, but only on 32-bit
x86 platforms - x86_64 seems to work fine as is.

Technically using &x and &y works too - but you're supposed to pass
in pointers to unsigned variables, so I went ahead and did that.
