ctest fails on the target, because it cannot find CMake.cmake inside
CMAKE_DATA_DIR (typically set to "/usr/share/cmake-3.0"): all *.cmake
files are removed at build time via the target-finalize rule.

This buildroot-specific patch makes sure ctest looks also for
"Modules/CMake.cmake.ctest" before complaining
