Fix misleading restart messages when plugin exceeds max_restarts

Fix UI issue where plugins would continue to show "was restarted"
messages even after exceeding the maximum restart limit.
Also, show how many times a plugin has been restarted.

Here is how it looked like before:
plugin /sbin/audisp-af_unix was restarted
plugin /sbin/audisp-af_unix terminated unexpectedly
plugin /sbin/audisp-af_unix was restarted --no such thing happened
