[2/2] cabinet.dll -> FDICopy: Bug fixed

[Vitaly Perov]

This is a bug fix for the FDICopy() function of cabinet.dll.
When you pass an empty cabinet file (It's correct cab-file, but it has no 
files and folders inside) as a parameter, Wine detects that the file is 
invalid.
In this case Windows return TRUE, but WINE return FALSE. So the installation 
of certain software finishes with an error in WINE.

Changelog:
    - Added a bug fix for cabinet.dll FDICopy function. Now it works correctly 
with an empty cab-files.
