[CMake] Always enable LOG_OUTPUT_ON_FAILUE in external projects

Logging what went wrong when building the builtins in the main CMake
output can significantly speed up identifying the problem when there is
a problem with builtins in the CI, or any other build environment where
is it not easy or even possible to access the auxiliary log files.

The `LOG_OUTPUT_ON_FAILURE` option was introduced in CMake 3.14 [1],
which is presumably the reason why this very useful option was not added
before.
