Proposed fix

Recent wine versions abort on startup if the config directory isn't owned by
the user running wine.

This breaks setups where several users share a common wine prefix (e.g. to make
applications that make heavy use of the registry available to several users
without installing them several times) and they have the right access to the
configs through group permissions.

Unless I'm overlooking a better way to do this, it would make more sense to
check proper permissions than to check ownership. I'm attaching a patch that
does that.
