TCP Wrappers: Use the Debian patches.

It has the following side effects (among others):

  * Fix compilation on x86_64.  We now only install the shared
    library and one of the Debian patches makes sure its objects
    are compiled with `-fPIC'.

  * Provide IPv6 support.

  * Fix man pages.

  * Fix `linux' makefile target.

+      Wietse Venema's network logger, also known as TCPD or LOG_TCP.
+      These programs log the client host name of incoming telnet, ftp,
+      rsh, rlogin, finger etc. requests.  Security options are: access
+      control per host, domain and/or service; detection of host name
+      spoofing or host address spoofing; booby traps to implement an
+      early-warning system.  The current version supports the System
+      V.4 TLI network programming interface (Solaris, DG/UX) in
+      addition to the traditional BSD sockets.
