wininet: Add test for FtpGetCurrentDirectoryA

[Zac Brown]

Hi,

Changelog:
* Add a test in dlls/wininet/tests/ftp.c for FtpGetCurrentDirectoryA

Notes:
* This test passes fully without error on Windows XP, with the test compiled by Visual Studio Express C++ 2008.
* The functions this test call are currently broken in wine and I am in the process of fixing them myself.

Patch is pasted below:
