Josef Schlehofer ddb23f3a02 tools/cmake: pass -DBUILD_TESTING=OFF to bootstrap 
Instead of carrying 100-no-testing.patch, pass -DBUILD_TESTING=OFF
directly to CMake's bootstrap script. This avoids refreshing the patch
on every CMake update.

The patch also changed the default in the installed CTest.cmake module.
Preserve that behavior by passing -DBUILD_TESTING=OFF by default in
cmake.mk for target and host builds. Packages can override it via
CMAKE_OPTIONS or CMAKE_HOST_OPTIONS.

OpenWrt never runs CMake tests, so building them only wastes build time.

This replaces the patch introduced in 8af80e79bd ("tools/cmake:
update to 3.17.0").
