This reverts commit af35741d3681f21222a85900b54d95ee422fe074.
As reported on IRC by user supermario1313, and bisected by Rounin, this commit made Wine no longer follow symlinks in Z:, which the former needs for a Wine-aware sandboxing solution.
I'm not a huge fan of the test, but I like leaving things untested even less. The Correct™ solution would be CreateSymbolicLink() or FSCTL_SET_REPARSE_POINT, but they're not implemented in Wine.
