KERNEL: [2/2] changed test for FindFirstFileEx

[Konstantin Petrov]

There were the problem while I advert to dosdevices through WINE. I made the 
test (Windows vs Wine), which shows that in Windows there are available 
dosfiles (such as NUL, COM1, COM2,.., LPT1, ..), and in Wine aren't. The 
characteristic property of these files is that I can advert to them only 
directly. In other cases they are invisible.

patch for test

changelog
	tests/file.c: added test of FindFirstFileA to check correct handling of 
advertments to dosdevices.
