CreateProcess gives us back a handle to the newly created process. Previously, we ignored this handle, which meant it was leaking every time we created a new job container (or anything else that uses internal/exec in the future). Process handle leaks can be bad as an exited process is left as a "zombie" until all handles to it have closed, continuing to use memory. Fix this by closing the handle from CreateProcess.
