win32: Fixed use of deprecated function 'GetVersionInfoEx' for VC12

Browse source 
Starting with Visual Studio 2013 (VC12) and Windows 8.1 the
GetVersionInfoEx() function has been marked as deprecated and it's
return value atered. Updated connect.c and curl_sspi.c to use
VerifyVersionInfo() where possible, which has been available since
Windows 2000.
