Stabilize os daemons test

Increase delay timeout to fix this failure:

```
**error:{assertNotEqual,[{module,couchdb_os_daemons_tests},
                 {line,207},
                 {expression,"D # daemon . kill"},
                 {value,undefined}]}
```

So far noticed this failure once out of more than 100 runs.
