In testing we're seeing sysklogd fail to restart klogd since the original
process hasn't stopped before the new one is started. This means a restart
can result in no process running which is clearly not desireable.
Add extra code to ensure this works correctly. Busybox start-stop-daemon
seems particularly open to this kind of issue, the dpkg version maybe
less so if timeout options are used (which we don't use).
