cmMakefile: Do not track CMake temporary files.

Since commit ad502502 (cmMakefile: Track configured files so we can
regenerate them, 2013-06-18) cmMakefile::ConfigureFile records the
configured file as an output file generated by CMake.  The intention is
that for make and ninja we can re-run CMake when one of the files it
generates goes missing.  However, files configured temporarily in
CMakeTmp directories by Check* modules do not live past the CMake
invocation.
