syslogd and klogd can occasionally take too long to restart, which
causes tests to fail by starting before the log daemons are ready. To
work around this problem, poll for up to 30 seconds on the processes to
verify the old ones are killed and the new ones are up and running.
Similarly, add checks for rsyslogd and systemd-journald to possibly
catch issues with those daemons.
