cmake: fix support for UnixSockets feature on Win32

Browse Source 
Move the definition of sockaddr_un struct from config-win32.h to
curl_setup.h, so that it could be shared by all build systems.

Add ADDRESS_FAMILY typedef for old mingw, now old mingw can also use
unix sockets.

Also fix the build of tests/server/sws.c on Win32 when USE_UNIX_SOCKETS
is defined.

Closes #7034
