[Piglit] [PATCH 05/14] cmake: Add FindWaffle.cmake

From: Adrian Marius Negreanu <adrian.m.negreanu at intel.com>

Piglit searches waffle by using pkg_check_modules.
If one tried to use the android toolchain along cmake,
waffle won't be found, since pkg_check_modules relies on
pkg-config(missing on android)

To fix this, add a "cmake find-module" for Waffle.

v2: Add version detection
v1: clean up the initial RFC patch
