Also try to use python-libdiscid

python-libdiscid is another libdiscid binding that also provides a python-discid
compatible interface in libdiscid.compat.discid.

The order of libdiscid and discid can be reversed of course, but then also OSError should be catched, i.e.
```python
try:
    import discid
except (ImportError, OSError):
    from libdiscid.compat import discid
```
