xcopy/tests: Fix the test in case stdin has been redirected.

[Francois Gouget]

On Windows 2003 and older xcopy exits prematurely if stdin does not 
point to the console, even when provided with the '/I /Y' options. 
Furthermore in that case the return code is 0 which trips up the test.
---

This explains why this test was failing on my test VMs: netcat redirects 
stdin/stdout to the socket before starting winetest.exe, thus triggering 
the above condition. The WineTestBot does not (currently) do that and 
thus has not been affected.
