Test the --cache-debug option to see if it prints the expected messages.

Note that we don't check for the "race condition" message when someone
else's build populates the CacheDir with a file in between the time we
to build it because it doesn't exist in the CacheDir, and the time our
build of the file completes and we push it out.
