While I'm debugging the kernel core file with lldb, lldb warns the following
message on 'quit' command. Note that pressing Ctl-d shows no warning messages.

```
Quitting LLDB will kill one or more processes. Do you really want to proceed: [Y/n]
```

It doesn't make sense to me. I'm not debugging any processes so the lldb won't
kill anything. And while I'm debugging the running kernel with
`lldb /bsd -c /dev/mem`, the 'quit' command also warns the same message but
the lldb won't stop the kernel, just quits normally. The warning message misses
the point.

So the following patch shuts up the warning message.
OK?
