os/exec: simplify TestContextCancel TestContextCancel is a test that ensures a process is killed soon after canceling the context, even if Wait is not called (#16222). The test checks whether the process exited without calling Wait by writing some data to its stdin. Currently the test involves two goroutines writing to stdin and reading from stdout. However the reading goroutine is not very necessary to detect the process exit. This patch simplifies the test by connecting the process stdout to /dev/null.
