autotools: allow unix sockets on Windows

Fixes: https://github.com/curl/curl-for-win/blob/73a070d96fd906fdee929e2f1f00a9149fb39239/curl-autotools.sh#L44-L47

On Windows this feature is present, but not the header used in the
detection logic. It also requires an elaborate enabler logic
(as seen in `lib/curl_setup.h`). Let's always allow it and let the
lib code deal with the details.

Closes #9688
