[monitoring-plugins/monitoring-plugin-perl] Add LONGOUTPUT parameter to plugin_exit (#9)

I'd like to be able to use something like the code below to emit additional
lines of LONGOUTPUT from a plugin.
```
$plugin->plugin_exit(OK, "All good", "additional\ndetails\nhere")
``` 
The output from this would be something like
```
OK - All good
additional
details
here|perfdata...
```
