Before this change, the shim was only publishing a non-zero exit status
(exit code) in the case that the process.Wait() call failed. This
grabs the exit status correctly when process.Wait() succeeds too.
When an exec occurs the pid was not properly updated on the in memory state
value causing many queries to see a 0.
