[PATCH v2] kernel32/tests: Allow failure when loading the 268 bytes minimal PE image.

[Francois Gouget]

Windows 10 1809+ rejects this minimal image so allow ERROR_BAD_EXE_FORMAT
as a valid result.
Also adjust the comment to reflect the range of Windows versions that
usually accept this image and note that there are some exceptions which
means there are other unidentified factors at play.

v2: Fixed v1's comment to match the platforms this test accutally 
    succeeds on.

w7u (32-bit Windows 7) rejects this image but not w7pro64.
cw-rx460 (64-bit Windows 8.1) also rejects this image but not
cw-gtx560, w8 and w864.
So this image is sometimes rejected by Windows versions that are
expected to accept it without the reason being known.
