Add final status line to run_tests.sh.

Now that run_tests.sh doesn't stop at the first failing test, we
need a final status line to tell us how many unittest files it ran
and how many passed/failed. This CL does that.

Last line of output now looks like this:

ALL TESTS PASSED (19 ran)  or 3 TESTS FAILED (out of 19)

BUG=chromium:570742
TEST=Tested in my directory.
