run-tests.sh: "-v" (verbose) flag

`run-tests.sh -v` will print the output from the test cases, even when
the test cases pass. This is useful for debugging test cases that are
reporting a pass when they are really failing. Having run-tests.sh print
the output directly saves me from hunting for /tmp/stb-tester.XXX/log.
