Remove "This incident will be reported." from user warnings.

This used to indicate that email had been sent to the administrator
telling them that someone tried to run sudo.  Whether or not sudo
sends email is now configurable, so the warning may not be accurate.
It is also confusing to the user since they will not know who the
incident is being reported to.  See also https://xkcd.com/838/
