Truly don't follow symlinks unless they are the only top-level path.

This is a brute-force hack which won't show them at all, there certainly
is better ways if we would know if we expanded paths ourselves or not.

 Thanks to [this PR](https://github.com/Byron/dua-cli/pull/37), hard links are now not counted anymore.
 The `-l` flag will count hard links as it did before. 
 
 And of course, this has no noticable performance impact.

 Thanks to [this PR](https://github.com/Byron/dua-cli/pull/35), the old apparent size can be displayed with the
 `-A` flag, and the much more useful 'size on disk' is now shown by default.
 
 To my pleasant surprise, this does not seem to affect performance at all - everything stays speedy.
