Cocoa: bugfix [#21158] fix modifiers keys status upon gaining focus

10.6 new function to get modifiers flags status asynchronously returns erroneous value when application gets focus after a virtual desktop switch (Spaces).
Use legacy method to retrieve the modifiers flags status sent with the last  event. Works as at least the "focus gained" event is sent before this query. Bonus: should work also on pre-10.6!
