[PATCH 1/3 resend] kernel32/tests: Test ReplaceFileW on open "exe"

[Brock York]

Replicate the scenario of an exe calling
ReplaceFileW on itself.
An exe calling ReplaceFileW on itself will fail
in Wine currently but succeed in Windows 7.
This seems to be the problem seen in bug 33845
where the WarFrame launcher will keep relaunching
itself because the launcher failed to replace
itself with the new version.
