wininet/tests: Don't include the trailing '\0' in dwHeadersLength otherwise HttpSendRequestEx() sends it too which some servers object to.

This fixes the wininet http tests on my Windows systems because they are 
on a special subnet on which I do some transparent proxying through 
Squid. And Squid happens to be a server which objects to malformed HTTP 
headers.
