[Piglit] [PATCH] cmake: Suppress warning on cmake 2.8.12+

[Dylan Baker]

cmake 2.8.12 Introduced a new policy (CMP0022). Because there are two
policy options and piglit doesn't explicitly ask for one it defaults to
the OLD setting, but spews warnings. By setting OLD explicitly this
warning goes away.
