cabinet.dll -> FDICopy: Test added

[Vitaly Perov]

(The code has been rewrited in according with recommendations by Dmitry 
Timoshkov)

This test check if function FDICopy() of cabinet.dll correctly works with an 
emty cabinet file (It's correct cab-files, but it has no files and folders 
inside).
In this case Windows return TRUE, but WINE return FALSE. So the installation 
of certain sofware finishes with an error in WINE

Changelog:
    - Added a test for cabinet.dll FDICopy function. This test check if it              
works correctly with an empty cab-files
