In this case (as the test is not requiring that specific header), you
can choose a different header that satisfies the requirement of the
test that works with the different versions of IE.

Alternatively, if this behaviour is on >= IE7, you could check for the
ERROR_WINHTTP_HEADER_NOT_FOUND return and issue a wine_skip (there are
examples of this in other tests).
