The mosquitto runtime test can randomly fail on slow runners, see [1]. This commit improves this test in the following ways: - the mosquitto_sub subscriber process is now started in a subshell to suppress the job control messages (to prevent any spurious messages when the job stops), - the standard error is redirected to /dev/null, to prevent the printing of any messages, - the mosquitto_pub publisher process is started later, by increasing the sleep time, - finally, a new sleep time is introduced between the mosquitto_pub publisher process and the check of the mosquitto_sub subscriber, to make sure it will have time to write its output and exit.
