cmake: cache HAVE_* results to skip feature checks on re-runs (#2137)

Without caching, HAVE_${VAR} was lost between cmake runs, so the
early-exit guard never fired and all feature test messages re-printed
on every reconfigure.

Now HAVE_${VAR} is written to the CMake cache (INTERNAL) on both
success and failure. Also fix the guard to not promote a cached 0 to 1.
