Subject: [Core] Workaround torrent file_progress lt 2.0 error

Workaround lt 2.0 python bindings error when calling a torrent handle
file_progress:

```
Boost.Python.ArgumentError: Python argument types in
    torrent_handle.file_progress(torrent_handle)
did not match C++ signature:
    file_progress(libtorrent::torrent_handle {lvalue}, libtorrent::flags::bitfield_flag<unsigned char, libtorrent::file_progress_flags_tag, void> flags=0)
```

Should be fixed in 2.0.5 release: https://github.com/arvidn/libtorrent/commit/3feba04e6d
