Default to 96dpi for the no config file case

[Mike Hearn]

Hi,

wineprefixcreate doesn't create a config file. This means we use a (wrong)
formula to decide what the DPI is supposed to be. It's wrong because
nobody tells the system how big their monitor is these days so it always
picks a DPI that is too small. 

It'd be worth figuring out how Windows calculates this, until then I found
the following patch handy.
