[PATCH] dinput : use vendor and product ids to generate product GUID like it's done on Windows

[Corentin Rossignon]

Hi, I will do a new patch with /* */ comment. I am using ditool.exe to 
display informations about DirectInput device. I found this tool on 
http://community.pcgamingwiki.com/files/file/588-directinputxinput-games-test-tools
