contrib: remove shadow-anonftp.patch

The patch is never applied upstream. If I were to take a gamble, I would
even say that it throws an error when trying to patch.

-Hello Marek,
-
-I have created a diffile against the 980403 release that adds
-functionality to newusers for automatic handling of users with only
-anonymous ftp login (using the guestgroup feature in ftpaccess, which
-means that the users home directory looks like '/home/user/./'). It also
-adds a commandline argument to specify an initial directory structure
-for such users, with a tarball normally containing the bin,lib,etc
-directories used in the chrooted environment.
-
-I am using it to automatically create chunks of users with only ftp
-access for a webserver.
-
-I have tried to follow your coding standards and I believe it is bug
-free but.. well, who knows. :) It's not much code however.
-
-I hope you find it useful. Do what you like with it, feel free to ask if
-anything is unclear.
-
-Best rgds,
