test/py: Provide output from exceptions with RunAndLog()
Tests may want to look at the output from running a command, even if it fails (e.g. with a non-zero return code). Provide a means to obtain this. Another approach would be to return a class object containing both the output and the exception, but I'm not sure if that would result in a lot of refactoring.
