Otherwise it's a pain to debug.
I'm trying to run homu in a container where it's installed (as root) to `/usr`, but we run as non-root. This follows general best practice that apps shouldn't be able to mutate their code. However, we were trying to write the ssh key to `/usr`. Fix this by generating a tempfile. This is also more secure as it closes a prior race condition where we'd write the file, then chown it. Also rework things so that we only write the key once at startup. By using `NamedTemporaryFile`, it'll be `unlink()ed` once the object goes out of scope. To keep it alive long enough, pass it as an argument to the "main loop".

@Manishearth would you mind reviewing this? |

I'm a bit swamped, but I'll queue it up. |
