Subject: [PATCH] test-report: Use color highlighting as in test-lib.

The test aggregate results are easy to miss when running the entire test suite via "make test", as the status of the last test case is highlighted, but the aggregate results appear in an unformatted, uncolored block of text.
Copy the say_color() function from test-lib.sh. (Sorry for the duplication, I found no simple way to import or share just this piece of functionality without adding much complexity.)
Successes, errors and broken summaries will now be highlighted in the appropriate colors (unless --no-color is given or output is not to a terminal), but only if the number is more than zero.
