crimson/alienstore: block SIGHUP to coexist with Seastar's signal handling.

In `crimson/osd/main.cc` we instruct Seastar to handle `SIGHUP`.

```
        // just ignore SIGHUP, we don't reread settings
        seastar::engine().handle_signal(SIGHUP, [] {})
```

This happens using the Seastar's signal handling infrastructure
which is incompliant with the alien world.

```
void
reactor::signals::handle_signal(int signo, noncopyable_function<void ()>&& handler) {
    // ...
    struct sigaction sa;
    sa.sa_sigaction = [](int sig, siginfo_t *info, void *p) {
        engine()._backend->signal_received(sig, info, p);
    };
    // ...
}
```

```
 extern __thread reactor* local_engine;
extern __thread size_t task_quota;

inline reactor& engine() {
    return *local_engine;
}
```

The low-level signal handler above assumes `local_engine._backend`
is not null which stays true only for threads from the S*'s world.
Unfortunately, as we don't block the `SIGHUP` for alien threads,
kernel is perfectly authorized to pick up one them to run the handler
leading to weirdly-looking segfaults like this one:
