The reason this test fails for me is because I have a FAT32 volume and
there is no ACL info stored, so the tests:

    ok(dacl != NULL, "GetSecurityInfo\n");
    ok(IsValidAcl(dacl), "GetSecurityInfo\n");

clearly will fail.  Unless there is another way to find out if the ACL
information is persistent, then the only option left is to remove
these tests otherwise they will always fail when running on a FAT32
drive.
