musl builds don't work with pyroute2

The title may be `problems with RTNL in musl builds`, but I don't know if it's accurate yet.

What I'm experiencing is that every usage I have with `pyroute2.IPRoute()` never returns (only on musl builds).

```
➜ ~ docker run --rm -it python:3.12-alpine /bin/sh -c "pip install uv; uvx --managed-python --with pyroute2 python -c \"import pyroute2; ipr = pyroute2.IPRoute(); [print(link['index']) for link in ipr.get_links()]\""

If I CTRL+C, this is the error I get (notice the `OSError: getsockaddrlen: bad family`, may be a lead)

### proof that it's a problem only with the musl builds here:
#### works fine with Python that was not built from this repo on musl
