slirp: drop <Vista compatibility

Since commit 12f8def0e02232d7c6416ad9b66640f973c531d1 (v2.9), qemu
requires Vista. Let's remove some conditional code.

Note that this introduces a missing declaration warning with mingw.
warning: implicit declaration of function 'inet_ntop'

See also: https://sourceforge.net/p/mingw-w64/mailman/message/36473782/

We could workaround it by declaring it ourself depending on __MINGW64_VERSION_*:
WINSOCK_API_LINKAGE INT WSAAPI inet_pton(int Family, PCTSTR pszAddrString, PVOID pAddrBuf);
