FindPackageMessage: Eliminate new lines in cache entries

Fix problem exposed by recent commit to FindPythonInterp.
If the find "details" has new lines in it, then replace them
with literal "\n" two character sequences so that the string
may be saved as a cache entry that can be re-read next time
CMake runs.
