sockets: fix Windows 2000 build (#450) 

Commit 4630a5dab6 broke compilation for
Windows 2000 and earlier as getaddrinfo was introduced in Windows XP.
Fix this by including <wspiapi.h> when targeting Windows 2000 and
earlier, which falls back to an inline implementation of getaddrinfo
when necessary.
Some MinGW flavors still target Windows 2000 by default.

section "Support for getaddrinfo on Windows 2000 and older versions"
