On Android, the exec wrapper passes on output from adb to its parent process by passing on os.Stderr and os.Stdout to adb. If the adb process somehow hangs, it will keep stderr and stdout will open, in turn blocking go test from ever returning from its cmd.Wait() even though it has killed the exec wrapper process. Break the short circuit by introducing a wrapper between adb and the exec wrapper, preventing os/exec.Run from passing along the raw file descriptors for os.Stdout and os.Stderr. (Hopefully) fixes occasional indefinite hangs on the Android builder.
