Add a workaround for failing test under Wine

Browse source 
Debugging confirms that DPtoLP() simply returns wrong (i.e. different
from that returned under actual MSW) result when using Wine, so just
account for it in the test as it seems to be better than just skipping
the test entirely under Wine and there doesn't seem to be anything else
to do.
