cgi: close stdout reader pipe when finished

This causes the child, if still writing, to get an error or
SIGPIPE and most likely exit so our subsequent wait can
finish.

A more guaranteed fix would be putting a time limit on the
child's overall execution, but this fixes the problem
I was having.

Fixes #2059
