NRPE return values

[Assaf Flatto]

The sudo was in place - but silly me - i forgot that the sudoers file has a specific list of 
commands that the nagios user have sudo permissions to run .

Adding the new script to the file did solve the issue.

But thank you for reminding me this slight oversight .
