Bug#629331: Mrtg Patch

[Jean-Louis Dupond]

Mrtg also needs to be patched.

Now it throws the following error:
Subroutine main::pack_sockaddr_in6 redefined at 
/usr/share/perl/5.14/Exporter.pm line 67. at /usr/bin/mrtg line 310

Attached the patch to fix this.--- mrtg.old    2013-05-15 16:37:53.982842509 +0200
